CVE-2026-59893: Andialbrecht Sqlparse

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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(). This issue is fixed in version 0.6.0.

Affected products

• Andialbrecht Sqlparse: before 0.6.0 (fixed in 0.6.0)
