NVD Description

Note: Versions mentioned in the description apply only to the upstream python311-sqlparse package and not the python311-sqlparse package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by group_parenthesis and group_case, causing quadratic CPU consumption through sqlparse.parse(), sqlparse.format(), and sqlparse.split() before depth and token limits terminate processing. This issue is fixed in version 0.6.0.
