High [CVE-2026-54284] Denial of Service via quadratic CPU consumption in SQL parsing
CVE-2026-54284Source published Source updated
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. A remote attacker could exploit a vulnerability in the TokenList construction and string conversion processes, specifically when handling nested token subtrees. This flaw leads to quadratic CPU consumption, which can result in a Denial of Service (DoS) by exhausting system resources before internal limits are reached. Red Hat severity: Important — CVSS 7.5…
