CVE-2026-71491

sqlparse (Python SQL parser) prior to 0.6.0 is vulnerable to a quadratic CPU DoS in group_comments (sqlparse/engine/grouping.py). A comment-only statement (e.g., '-- c\n' * n) causes the function to rescan all remaining tokens per iteration, yielding O(n²) behavior. Critically, this runs before t...
