The python-black package is susceptible to a regular expression denial of service (ReDoS) vulnerability, found in the lines_with_leading_tabs_expanded() function within the strings.py file. This vulnerability could be exploited by running Black on untrusted input or by inserting numerous leading tab characters into docstrings. This flaw allows attackers to craft malicious input to trigger a denial of service.
