# Contributing to Pillow
Bug fixes, feature additions, tests, documentation and more can be contributed via [issues](https://github.com/python-pillow/Pillow/issues) and/or [pull requests](https://github.com/python-pillow/Pillow/pulls). All contributions are welcome.
## Bug fixes, feature additions, etc.
Please send a pull request to the `main` branch. Please include [documentation](https://pillow.readthedocs.io) and [tests](../Tests/README.rst) for new features. Tests or documentation without bug fixes or feature additions are welcome too. Feel free to ask questions [via issues](https://github.com/python-pillow/Pillow/issues/new), [discussions](https://github.com/python-pillow/Pillow/discussions/new), [Gitter](https://gitter.im/python-pillow/Pillow) or irc://irc.freenode.net#pil
- Fork the Pillow repository.
- Create a branch from `main`.
- Develop bug fixes, features, tests, etc.
- Run the test suite. You can enable GitHub Actions (https://github.com/MY-USERNAME/Pillow/actions) on your repo to catch test failures prior to the pull request, and [Codecov](https://codecov.io/gh) to see if the changed code is covered by tests.
- Create a pull request to pull the changes from your branch to the Pillow `main`.
### Guidelines
- Separate code commits from reformatting commits.
- Provide tests for any newly added code.
- Follow PEP 8.
- When committing only documentation changes please include `[ci skip]` in the commit message to avoid running extra tests.
- Include [release notes](https://github.com/python-pillow/Pillow/tree/main/docs/releasenotes) as needed or appropriate with your bug fixes, feature additions and tests.
## Reporting Issues
When reporting issues, please include code that reproduces the issue and whenever possible, an image that demonstrates the issue. Please upload images to GitHub, not to third-party file hosting sites. If necessary, add the image to a zip or tar archive.
The best reproductions are self-contained scripts with minimal dependencies. If you are using a framework such as plone, Django, or buildout, try to replicate the issue just using Pillow.
### Provide details
- What did you do?
- What did you expect to happen?
- What actually happened?
- What versions of Pillow and Python are you using?
## Security vulnerabilities
Please see our [security policy](https://github.com/python-pillow/Pillow/blob/main/.github/SECURITY.md).

# Incident Response Plan — Pillow
This document describes how the Pillow maintainers detect, triage, fix, communicate, and
learn from security incidents. It supplements the existing [Security Policy](SECURITY.md)
and [Release Checklist](../RELEASING.md).
---
## 1. Preparation
Maintaining readiness before an incident occurs reduces response time and errors under pressure.
### 1.1 Version Support Matrix
Security fixes are applied to the **latest stable release only**. Users on older versions
are expected to upgrade. Reporters should assume only the latest release will receive a patch.
| Branch | Status |
|---|---|
| `main` / latest stable | ✅ Security fixes applied |
| All older releases | ❌ No security support — please upgrade |
### 1.2 Team Readiness
The four members of the Pillow core team are in regular contact and share collective
responsibility for incident response. Any core team member may act as Incident Lead.
Contact details are known to all team members.
### 1.3 Readiness Review
At each quarterly release, maintainers should re-read this document and update any stale content.
---
## 2. Scope
This plan covers:
| Incident type | Examples |
|---|---|
| Vulnerability in Pillow's own Python or C code | Buffer overflow in an image decoder, integer overflow in `ImagingNew` |
| Vulnerability in a bundled or wheel-shipped C library | libjpeg, libwebp, libtiff, libpng, openjpeg, libavif |
| Supply-chain compromise | Malicious commit, stolen maintainer credentials, tampered PyPI wheel |
| CI/CD or infrastructure compromise | GitHub Actions secret leak, Codecov breach, PyPI token exposure |
| Critical non-security regression | Data-loss bug shipped in a release, crash on all supported platforms |
---
## 3. Definitions
| Term | Meaning |
|---|---|
| **Incident** | Any event that compromises or threatens the confidentiality, integrity, or availability of Pillow's code, release artifacts, or infrastructure. |
| **Vulnerability** | A security flaw in Pillow or a bundled library that can be exploited by a crafted image or API call. |
| **Incident Lead** | The maintainer who owns coordination of the response from triage to closure. |
| **Embargo** | A period during which fix details are kept private to allow coordinated patching before public disclosure. |
| **Yank** | A PyPI action that keeps a release downloadable by pinned users but removes it from default `pip install` resolution. |
| **CVE** | Common Vulnerabilities and Exposures — a public identifier assigned to a specific vulnerability. |
| **CNA** | CVE Numbering Authority — GitHub is a CNA and can assign CVEs directly through the advisory workflow. |
---
## 4. Roles
| Role | Responsibility |
|---|---|
| **Incident Lead** | First maintainer to triage the report. Owns the incident until resolution. |
| **Patch Owner** | Writes and tests the fix (may be the same person as Incident Lead). |
| **Release Manager** | Cuts the point release following [RELEASING.md](../RELEASING.md). |
| **Communications Owner** | Drafts the GitHub Security Advisory, announces on Mastodon, notifies distros. |
| **Tidelift Contact** | For reports that arrive via Tidelift, coordinate through the Tidelift security portal. |
One person may fill multiple roles.
---
## 5. Severity Classification
Use the [CVSS 4.0](https://www.first.org/cvss/v4.0/specification-document) base score as
a guide, mapped to the following levels:
| Severity | CVSS | Definition | Target Response SLA |
|---|---|---|---|
| **Critical** | 9.0 10.0 | Remote code execution, arbitrary write, or complete integrity/confidentiality loss achievable by opening a crafted image | Best effort; embargoed release where possible |
| **High** | 7.0 8.9 | Heap/stack buffer overflow, use-after-free, or significant information disclosure | Best effort |
| **Medium** | 4.0 6.9 | Denial of service via crafted image, out-of-bounds read, limited info disclosure | Next scheduled quarterly release, or earlier point release if needed |
| **Low** | 0.1 3.9 | Minor information disclosure, unlikely to be exploitable in practice | Next quarterly release |
Supply-chain and CI/CD incidents are always treated as **Critical** regardless of CVSS.
> **Note:** These are good-faith targets for a small volunteer maintainer team, not contractual SLAs. Public safety and transparency will always be prioritised, even when timing varies.
---
## 6. Detection Sources
Vulnerabilities and incidents may be reported or discovered through:
1. **GitHub private security advisory** — preferred channel; see [SECURITY.md](SECURITY.md)
2. **Tidelift security contact**<https://tidelift.com/docs/security>
3. **External researcher / coordinated disclosure** — e.g. Google Project Zero, vendor PSIRT
4. **Automated scanning** — Dependabot, GitHub code-scanning (CodeQL), CI fuzzing
5. **Distro security teams** — Debian, Red Hat, Ubuntu, Alpine may report upstream
6. **User bug report** — public issue (reassess if it has security implications and convert to a private advisory if needed)
---
## 7. Response Process
### 7.1 Triage (all severities)
1. **Acknowledge receipt** to the reporter within **72 hours** using the template in
[Appendix A](#appendix-a-communication-templates). Ask the reporter:
- How they would like to be credited (name, handle, or anonymous)
- Whether they intend to publish their own advisory, and if so, their preferred timeline
- Thank them explicitly — reporters do the project a favour by disclosing privately.
2. Reproduce the issue. If the report is invalid, close it and notify the reporter.
3. Assign a severity level ([Section 5: Severity Classification](#5-severity-classification)).
4. If the GitHub Security Advisory was not created by the reporter, create one now and keep
it **private** until the fix is released. Add the reporter as a collaborator if they wish
to be involved.
5. **Request a CVE** through the GitHub Security Advisory workflow (GitHub is a CVE
Numbering Authority — no separate MITRE form required). The CVE is reserved privately
and published automatically when the advisory goes public.
6. **Escalation** — Escalate beyond the core maintainer team if any of the following apply:
- The fix requires changes to CPython or a dependency outside Pillow's control → contact the relevant upstream immediately
- A legal concern arises (e.g. GDPR-reportable data exposure) → contact the project's legal/fiscal sponsor
- The Incident Lead is unreachable for > 24 hours on a Critical issue → any other maintainer may assume the role
### 7.2 Fix Development
1. Develop the fix in a **private fork** or directly in the private security advisory
workspace on GitHub. Do **not** push to a public branch before the embargo lifts.
2. Write a regression test that fails before the fix and passes after.
3. Review the patch with at least one other maintainer.
### 7.3 Standard (Non-Embargoed) Release
For Medium and Low severity, or when no distro pre-notification is needed:
1. Merge the fix to `main`, then cherry-pick to all affected release branches
(see [RELEASING.md — Point release](../RELEASING.md)).
2. Amend commit messages to include the CVE identifier.
3. Follow the [Point release](../RELEASING.md#point-release) process in RELEASING.md to
tag, push, and confirm wheels are live on PyPI.
4. Publish the GitHub Security Advisory (this simultaneously publishes the CVE).
### 7.4 Embargoed Release
For Critical and High severity where distro pre-notification improves user safety:
1. Prepare patches against all affected release branches and test locally.
2. Agree on an **embargo date** with the reporter (typically 714 days out, up to 90 days for
complex issues).
3. Privately send the patch to distros via the
[linux-distros](https://oss-security.openwall.org/wiki/mailing-lists/distros) mailing list
or directly to individual distro security teams.
4. On the embargo date:
- Amend commit messages with the CVE identifier.
- Follow the [Embargoed release](../RELEASING.md#embargoed-release) process in
RELEASING.md to tag, push, and confirm wheels are live on PyPI.
- Publish the GitHub Security Advisory.
### 7.5 Supply-Chain / Infrastructure Compromise
1. **Immediately** revoke any potentially compromised credentials:
- PyPI API tokens
- GitHub personal access tokens and OAuth apps
- Codecov or other CI service tokens
2. Audit recent commits and releases for tampering:
- Verify release tags against known-good SHAs
- Re-inspect any wheel published since the potential compromise window
3. If a PyPI release is suspected to be tampered: yank it immediately via the
[PyPI release management page](https://pypi.org/manage/project/Pillow/releases/)
(login required); see [https://pypi.org/security/](https://pypi.org/security/) for
reporting to the PyPI security team.
4. Issue a public advisory describing the scope and any user action required.
### 7.6 Recovery
After the fix is released and the advisory is public:
1. Verify that the patched wheels are live on PyPI and passing CI across all supported platforms.
2. Confirm any yanked releases are handled correctly .
3. Resume normal development operations on `main`.
4. Monitor the GitHub issue tracker and Mastodon for user reports of residual problems for at least **72 hours** post-release.
5. Close the private GitHub Security Advisory once recovery is confirmed.
---
## 8. Communication
### Internal (during embargo)
- Use the **private GitHub Security Advisory** thread for coordination with the reporter.
- Use private communication channels for all other coordination.
- Do not discuss details in public issues, PRs, or Gitter/IRC channels.
### External (at or after disclosure)
| Audience | Channel | Timing |
|---|---|---|
| General users | [GitHub Security Advisory](https://github.com/python-pillow/Pillow/security/advisories) | At release |
| PyPI ecosystem | CVE published via advisory | At release |
| Downstream distros | Direct email or linux-distros list | Before embargo date (embargoed) |
| Tidelift subscribers | Tidelift security portal | At release (or coordinated) |
| Community | [Mastodon @pillow](https://fosstodon.org/@pillow) | At release |
**Advisory content should include:**
- CVE identifier and CVSS score
- Affected Pillow versions
- Fixed version(s)
- Nature of the vulnerability (without full exploit details if still fresh)
- Credit to the reporter (with their consent)
- Upgrade instructions (`python3 -m pip install --upgrade Pillow`)
---
## 9. Dependency Map
Understanding what Pillow depends on (upstream) and what depends on Pillow (downstream)
is essential for scoping impact and coordinating notifications during an incident.
### 9.1 Upstream Dependencies
#### Bundled C libraries (shipped in official wheels)
These libraries are compiled into Pillow's binary wheels. A CVE in any of them may
require a Pillow point release even if Pillow's own code is unchanged.

| [libyuv](https://chromium.googlesource.com/libyuv/libyuv/) | YUV conversion | [Chromium tracker](https://libyuv.issues.chromium.org/issues) |
#### Python-level dependencies
| Package | Required? | Purpose |
|---|---|---|
| `setuptools` | Build-time only | Package build backend |
| `pybind11` | Build-time only | Compile C files in parallel |
| `olefile` | Optional (`fpx`, `mic` extras) | OLE2 container parsing (FPX, MIC formats) |
| `defusedxml` | Optional (`xmp` extra) | Safe XML parsing for XMP metadata |
See [`pyproject.toml`](../pyproject.toml) for the complete and authoritative list of
optional dependencies.
### 9.2 Responding to an Upstream Vulnerability
When a CVE is published for a bundled C library:
1. Assess whether the vulnerable code path is reachable through Pillow's API.
2. If reachable, treat as a Pillow vulnerability and follow [Section 5: Severity Classification](#5-severity-classification).
3. Update the bundled library version in the wheel build scripts and rebuild wheels.
4. Reference the upstream CVE in Pillow's release notes and GitHub Security Advisory.
5. If not reachable, document the rationale in a public issue so downstream distributors
can make informed decisions about patching their system packages.
### 9.3 Downstream Dependencies
A vulnerability in Pillow can have wide impact. Notify or consider the blast radius of
these downstream consumers when assessing severity and planning communications.
#### Linux distribution packages
| Distribution | Package name | Security contact |
|---|---|---|
| Debian / Ubuntu | `python3-pil` | [Debian Security](https://www.debian.org/security/) / [Ubuntu Security](https://ubuntu.com/security) |
| Fedora / RHEL / CentOS | `python3-pillow` | [Red Hat Security](https://access.redhat.com/security/) |
| Alpine Linux | `py3-pillow` | [Alpine security](https://security.alpinelinux.org/) |
| Arch Linux | `python-pillow` | [Arch security tracker](https://security.archlinux.org/) |
| Homebrew | `pillow` | [Homebrew maintainers](https://github.com/Homebrew/homebrew-core/security) |
| conda-forge | `pillow` | [conda-forge](https://github.com/conda-forge/pillow-feedstock) |
#### Major Python ecosystem consumers
These are high-profile projects known to depend on Pillow; a critical vulnerability may
warrant proactive notification.
| Project | Usage |
|---|---|
| [matplotlib](https://matplotlib.org/) | Image I/O for plots |
| [scikit-image](https://scikit-image.org/) | Image processing |
| [torchvision](https://github.com/pytorch/vision) (PyTorch) | Dataset loading, transforms |
| [Keras / TensorFlow](https://keras.io/) | Image preprocessing utilities |
| [Django](https://www.djangoproject.com/) | `ImageField` validation and thumbnail generation |
| [Wagtail](https://wagtail.org/) | CMS image renditions |
| [Plone](https://plone.org/) | CMS image handling |
| [Jupyter / IPython](https://jupyter.org/) | Inline image display |
| [ReportLab](https://www.reportlab.com/) | PDF image embedding |
| [Tidelift subscribers](https://tidelift.com/) | Enterprise consumers (coordinated via Tidelift) |
#### Pillow ecosystem plugins
Third-party plugins extend Pillow and are distributed separately on PyPI. Their
maintainers should be notified for Critical/High issues that affect the plugin API
or the formats they decode. See the
[full plugin list](https://pillow.readthedocs.io/en/stable/handbook/third-party-plugins.html#plugin-list).
---
## 11. Plan Maintenance
This document is a living record. It should be kept current so it is useful when an incident actually occurs. Revisit it during the [Section 1.3 readiness review](#13-readiness-review) at each quarterly release.

<!--
Thank you for reporting an issue.
Follow these guidelines to ensure your issue is handled properly.
If you have a ...
1. General question: consider asking the question on Stack Overflow
with the python-imaging-library tag:
* https://stackoverflow.com/questions/tagged/python-imaging-library
Do not ask a question in both places.
If you think you have found a bug or have an unexplained exception
then file a bug report here.
2. Bug report: include a self-contained, copy-pastable example that
generates the issue if possible. Be concise with code posted.
Guidelines on how to provide a good bug report:
* https://stackoverflow.com/help/mcve
Bug reports which follow these guidelines are easier to diagnose,
and are often handled much more quickly.
3. Feature request: do a quick search of existing issues
to make sure this has not been asked before.
We know asking good questions takes effort, and we appreciate your time.
Thank you.
-->
### What did you do?
### What did you expect to happen?
### What actually happened?
### What are your OS, Python and Pillow versions?
* OS:
* Python:
* Pillow:
```text
Please paste here the output of running:
python3 -m PIL.report
or
python3 -m PIL --report
Or the output of the following Python code:
from PIL import report
# or
from PIL import features
features.pilinfo(supported_formats=False)
```
<!--
Please include **code** that reproduces the issue and whenever possible, an **image** that demonstrates the issue. Please upload images to GitHub, not to third-party file hosting sites. If necessary, add the image to a zip or tar archive.
The best reproductions are self-contained scripts with minimal dependencies. If you are using a framework such as Plone, Django, or Buildout, try to replicate the issue just using Pillow.

name: "Maintainers only: Release"
about: For maintainers to schedule a quarterly release
labels: Release
---
## Main release
Released quarterly on January 2nd, April 1st, July 1st and October 15th.
* [ ] Open a release ticket e.g. https://github.com/python-pillow/Pillow/issues/3154
* [ ] Develop and prepare release in `main` branch.
* [ ] Add release notes e.g. https://github.com/python-pillow/Pillow/pull/8885
* [ ] Check [GitHub Actions](https://github.com/python-pillow/Pillow/actions) to confirm passing tests in `main` branch.
* [ ] Check that all the wheel builds pass the tests in the [GitHub Actions "Wheels" workflow](https://github.com/python-pillow/Pillow/actions/workflows/wheels.yml) jobs by manually triggering them.
* [ ] In compliance with [PEP 440](https://peps.python.org/pep-0440/), update version identifier in `src/PIL/_version.py`
* [ ] Run pre-release check via `make release-test` in a freshly cloned repo.
* [ ] Create branch and tag for release e.g.:
```bash
git branch [[MAJOR.MINOR]].x
git tag [[MAJOR.MINOR]].0
git push --tags
```
* [ ] Check the [GitHub Actions "Wheels" workflow](https://github.com/python-pillow/Pillow/actions/workflows/wheels.yml) has passed, including the "Upload release to PyPI" job. This will have been triggered by the new tag.
* [ ] Publish the [release on GitHub](https://github.com/python-pillow/Pillow/releases).
* [ ] In compliance with [PEP 440](https://peps.python.org/pep-0440/), increment and append `.dev0` to version identifier in `src/PIL/_version.py` and then:
```bash
git push --all
```
## Publicize release
* [ ] Announce release availability via [Mastodon](https://fosstodon.org/@pillow) e.g. https://fosstodon.org/@pillow/110639450470725321
## Documentation
* [ ] Make sure the [default version for Read the Docs](https://pillow.readthedocs.io/en/stable/) is up-to-date with the release changes
## Docker images
* [ ] Update Pillow in the Docker Images repository
```bash
git clone https://github.com/python-pillow/docker-images
cd docker-images
./update-pillow-tag.sh [[release tag]]
```

# Security policy
## Reporting a vulnerability
To report sensitive vulnerability information, report it [privately on GitHub](https://github.com/python-pillow/Pillow/security/advisories/new).
If you cannot use GitHub, use the [Tidelift security contact](https://tidelift.com/docs/security). Tidelift will coordinate the fix and disclosure.
**DO NOT report sensitive vulnerability information in public.**
## Threat model
Pillow's primary attack surface is parsing untrusted image data. A full STRIDE threat model covering spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege is maintained in the [Security handbook page](https://pillow.readthedocs.io/en/latest/handbook/security.html).
Key risks to be aware of when using Pillow to process untrusted images:
- **Decompression bombs** — do not set `Image.MAX_IMAGE_PIXELS = None` in production.
- **EPS files invoke Ghostscript** — block EPS input at the application layer unless strictly required.
- **`ImageMath.unsafe_eval()`** — never pass user-controlled strings to this function; use `lambda_eval` instead.
- **C extension memory safety** — keep Pillow and its bundled C libraries (libjpeg, libpng, libtiff, libwebp, etc.) up to date.
- **Sandboxing** — for high-risk deployments, run image processing in a sandboxed subprocess.
