3.1.5

This is the Jinja 3.1.5 security fix release, which fixes security issues and bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

Changes: https://jinja.palletsprojects.com/changes/#version-3-1-5
Milestone: https://github.com/pallets/jinja/milestone/16?closed=1

• The sandboxed environment handles indirect calls to str.format, such as by passing a stored reference to a filter that calls its argument. GHSA-q2x7-8rv6-6q7h
• Escape template name before formatting it into error messages, to avoid issues with names that contain f-string syntax. #1792, GHSA-gmj6-6f8f-6699

• Avoid leaving root_render_func() unclosed in Template.generate_async. #1960
• Avoid leaving async generators unclosed in blocks, includes and extends. #1960
• The runtime uses the correct concat function for the current environment when calling block references. #1701
• Make |unique async-aware, allowing it to be used after another async-aware filter. #1781
• |int filter handles OverflowError from scientific notation. #1921
• Make compiling deterministic for tuple unpacking in a {% set ... %} call. #2021
• Fix dunder protocol (copy/pickle/etc) interaction with Undefined objects. #2025

• Tests decorated with @pass_context can be used with the |select filter. #1624
• Using set for multiple assignment (a, b = 1, 2) does not fail when the target is a namespace attribute. #1413
• Using set in all branches of {% if %}{% elif %}{% else %} blocks does not cause the variable to be considered initially undefined. #1253

3.1.4

This is the Jinja 3.1.4 security release, which fixes security issues and bugs but does not otherwise change behavior and should not result in breaking changes.

PyPI: https://pypi.org/project/Jinja2/3.1.4/
Changes: https://jinja.palletsprojects.com/en/3.1.x/changes/#version-3-1-4

• The xmlattr filter does not allow keys with / solidus, > greater-than sign, or = equals sign, in addition to disallowing spaces. Regardless of any validation done by Jinja, user input should never be used as keys to this filter, or must be separately validated first. GHSA-h75v-3vvj-5mfj

3.1.3

This is a fix release for the 3.1.x feature branch.

• Fix for GHSA-h5c8-rqwp-cp95. You are affected if you are using xmlattr and passing user input as attribute keys.

This is a feature release, which includes new features and removes previously deprecated features. The 3.1.x branch is now the supported bugfix branch, the 3.0.x branch has become a tag marking the end of support for that branch. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. We also encourage upgrading to MarkupSafe 2.1.1, the latest version at this time.
