SQL injection via unbound cache prefix
Published Jul 14, 2026 · Updated Jul 14, 2026
SQL injection in Symfony Cache allows attackers to alter cache deletion queries through a caller-controlled clear() prefix. In PdoAdapter::doClear(), the non-versioning path interpolates the derived namespace into a DELETE LIKE literal and executes it with PDO::exec() without binding or escaping. Exploitation requires an application path that passes attacker-influenced data to clear($prefix), enabling deletion beyond the intended cache-key prefix or other changes to query semantics.
