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
  • 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)
