CVE-2026-59893
Last modified
CVE-2026-59893 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, SQL_REGEX in sqlparse/keywords.py and the per-position loop in sqlparse/lexer.py repeatedly scan unmatched dollar-quoted literal and multiline-comment delimiters, causing quadratic CPU consumption through sqlparse.parse(), sqlparse.format(), and sqlparse.split(). EPSS estimates a 0.28% chance of exploitation in the next 30 days.
