NVD Description

Note: Versions mentioned in the description apply only to the upstream python-sqlparse package and not the python-sqlparse package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
