Black vulnerable to Regular Expression Denial of Service (ReDoS)

CVE-2024-21503 / GHSA-fj7x-q9j7-g6q6 / PYSEC-2024-48

More information

Details

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.

Severity

• CVSS Score: 5.3 / 10 (Medium)
• Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L

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)
