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.
