GitHub Vulnerability Alerts

CVE-2024-21503

Versions of the package black before 24.3.0 are vulnerable to Regular Expression Denial of Service (ReDoS) via the lines_with_leading_tabs_expanded function in the strings.py file. An attacker could exploit this vulnerability by crafting a malicious input that causes a denial of service.

Exploiting this vulnerability is possible when running Black on untrusted input, or if you habitually put thousands of leading tab characters in your docstrings.

Release Notes

psf/black (black)

`v24.3.0`

Compare Source

Highlights

This release is a milestone: it fixes Black's first CVE security vulnerability. If you
run Black on untrusted input, or if you habitually put thousands of leading tab
characters in your docstrings, you are strongly encouraged to upgrade immediately to fix
CVE-2024-21503.

This release also fixes a bug in Black's AST safety check that allowed Black to make
incorrect changes to certain f-strings that are valid in Python 3.12 and higher.

Stable style

Don't move comments along with delimiters, which could cause crashes (#4248)
Strengthen AST safety check to catch more unsafe changes to strings. Previous versions
of Black would incorrectly format the contents of certain unusual f-strings containing
nested strings with the same quote type. Now, Black will crash on such strings until
support for the new f-string syntax is implemented. (#4270)
Fix a bug where line-ranges exceeding the last code line would not work as expected
(#4273)

Performance

Fix catastrophic performance on docstrings that contain large numbers of leading tab
characters. This fixes
CVE-2024-21503.
(#4278)

Documentation

Note what happens when --check is used with --quiet (#4236)

`v24.2.0`

Compare Source

Stable style

Fixed a bug where comments where mistakenly removed along with redundant parentheses
(#4218)

Preview style

Move the hug_parens_with_braces_and_square_brackets feature to the unstable style
due to an outstanding crash and proposed formatting tweaks (#4198)
Fixed a bug where base expressions caused inconsistent formatting of ** in tenary
expression (#4154)
Checking for newline before adding one on docstring that is almost at the line limit
(#4185)
Remove redundant parentheses in case statement if guards (#4214).

Configuration

Fix issue where Black would ignore input files in the presence of symlinks (#4222)
Black now ignores pyproject.toml that is missing a tool.black section when
discovering project root and configuration. Since Black continues to use version
control as an indicator of project root, this is expected to primarily change behavior
for users in a monorepo setup (desirably). If you wish to preserve previous behavior,
simply add an empty [tool.black] to the previously discovered pyproject.toml
(#4204)

Output

Black will swallow any SyntaxWarnings or DeprecationWarnings produced by the ast
module when performing equivalence checks (#4189)

Integrations

Add a JSONSchema and provide a validate-pyproject entry-point (#4181)

`v24.1.1`

Compare Source

Bugfix release to fix a bug that made Black unusable on certain file systems with strict
limits on path length.

Preview style

Consistently add trailing comma on typed parameters (#4164)

Configuration

Shorten the length of the name of the cache file to fix crashes on file systems that
do not support long paths (#4176)

`v24.1.0`

Compare Source

Highlights

This release introduces the new 2024 stable style (#4106), stabilizing the following
changes:

Add parentheses around if-else expressions (#2278)
Dummy class and function implementations consisting only of ... are formatted more
compactly (#3796)
If an assignment statement is too long, we now prefer splitting on the right-hand side
(#3368)
Hex codes in Unicode escape sequences are now standardized to lowercase (#2916)
Allow empty first lines at the beginning of most blocks (#3967, #4061)
Add parentheses around long type annotations (#3899)
Enforce newline after module docstrings (#3932, #4028)
Fix incorrect magic trailing comma handling in return types (#3916)
Remove blank lines before class docstrings (#3692)
Wrap multiple context managers in parentheses if combined in a single with statement
(#3489)
Fix bug in line length calculations for power operations (#3942)
Add trailing commas to collection literals even if there's a comment after the last
entry (#3393)
When using --skip-magic-trailing-comma or -C, trailing commas are stripped from
subscript expressions with more than 1 element (#3209)
Add extra blank lines in stubs in a few cases (#3564, #3862)
Accept raw strings as docstrings (#3947)
Split long lines in case blocks (#4024)
Stop removing spaces from walrus operators within subscripts (#3823)
Fix incorrect formatting of certain async statements (#3609)
Allow combining # fmt: skip with other comments (#3959)

There are already a few improvements in the --preview style, which are slated for the
2025 stable style. Try them out and
share your feedback. In the past, the preview
style has included some features that we were not able to stabilize. This year, we're
adding a separate --unstable style for features with known problems. Now, the
--preview style only includes features that we actually expect to make it into next
year's stable style.

Stable style

Several bug fixes were made in features that are moved to the stable style in this
release:

Fix comment handling when parenthesising conditional expressions (#4134)
Fix bug where spaces were not added around parenthesized walruses in subscripts,
unlike other binary operators (#4109)
Remove empty lines before docstrings in async functions (#4132)
Address a missing case in the change to allow empty lines at the beginning of all
blocks, except immediately before a docstring (#4130)
For stubs, fix logic to enforce empty line after nested classes with bodies (#4141)

Preview style

Add --unstable style, covering preview features that have known problems that would
block them from going into the stable style. Also add the --enable-unstable-feature
flag; for example, use
--enable-unstable-feature hug_parens_with_braces_and_square_brackets to apply this
preview feature throughout 2024, even if a later Black release downgrades the feature
to unstable (#4096)
Format module docstrings the same as class and function docstrings (#4095)
Fix crash when using a walrus in a dictionary (#4155)
Fix unnecessary parentheses when wrapping long dicts (#4135)
Stop normalizing spaces before # fmt: skip comments (#4146)

Configuration

Print warning when configuration in pyproject.toml contains an invalid key (#4165)
Fix symlink handling, properly ignoring symlinks that point outside of root (#4161)
Fix cache mtime logic that resulted in false positive cache hits (#4128)
Remove the long-deprecated --experimental-string-processing flag. This feature can
currently be enabled with --preview --enable-unstable-feature string_processing.
(#4096)

Integrations

Revert the change to run Black's pre-commit integration only on specific git hooks
(#3940) for better compatibility with older versions of pre-commit (#4137)

Packaging

Fixed a bug that included dependencies from the d extra by default (#4108)

`v23.12.0`

Highlights

It's almost 2024, which means it's time for a new edition of Black's stable style!
Together with this release, we'll put out an alpha release 24.1a1 showcasing the draft
2024 stable style, which we'll finalize in the January release. Please try it out and
share your feedback.

This release (23.12.0) will still produce the 2023 style. Most but not all of the
changes in --preview mode will be in the 2024 stable style.

Stable style

Fix bug where # fmt: off automatically dedents when used with the --line-ranges
option, even when it is not within the specified line range. (#4084)

`v23.9.1`

Compare Source

Due to various issues, the previous release (23.9.0) did not include compiled mypyc
wheels, which make Black significantly faster. These issues have now been fixed, and
this release should come with compiled wheels once again.

There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12
wheels in a future release as soon as the mypyc bug is fixed.

Packaging

`v23.3.0`

Compare Source

Highlights

This release fixes a longstanding confusing behavior in Black's GitHub action, where the

addition, there is a small bug fix around imports and a number of improvements to the
preview style.

Please try out the
preview style
with black --preview and tell us your feedback. All changes in the preview style are
expected to become part of Black's stable style in January 2024.
