Because backslash is the default LIKE escape character, the escaping defeats itself: the input \\% becomes the pattern fragment \\\\%, where \\\\ is a literal backslash and the attacker's % remains a live wildcard. The search value stays parameterized, so this is confined to the LIKE pattern grammar rather than full SQL. An attacker can widen matches to probe values, slip past a negated contains(...) guard, or crash the query with a trailing lone backslash.\n\nThis issue affects ash_sql: from 0.1.1-rc.10 before 0.7.1."}], "lastModified": "2026-09-01T21:15:00.147", "sourceIdentifier": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db"}
