CVE-2026-59894

A flaw was found in sqlparse, a non-validating SQL parser module for Python. When generating Python or PHP code snippets, the sqlparse.format function fails to properly escape backslashes before quotes in SQL strings. This vulnerability allows a local attacker, by providing crafted SQL, to break...

CVE-2026-71491

A flaw was found in sqlparse, a Python module for parsing SQL. A remote attacker could exploit this vulnerability by providing specially crafted SQL input that contains numerous comment-only statements. This could cause the groupcomments function to repeatedly rescan these statements, leading to...

CVE-2026-59893

A flaw was found in sqlparse, a Python module for parsing SQL. A remote attacker could exploit this vulnerability by providing specially crafted SQL input. This flaw causes inefficient processing of certain SQL patterns, leading to excessive CPU consumption and potentially a Denial of Service DoS...
