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.

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
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)

with other comments (#3959)There are already a few improvements in the
--preview
style, which are slated for the2025 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 nextyear's stable style.
Stable style
Several bug fixes were made in features that are moved to the stable style in this
release:

to apply thispreview feature throughout 2024, even if a later Black release downgrades the feature
to unstable (#4096)

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.
