This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete any arbitrary Filter Gallery records \u2014 including all associated filters, image mappings, settings, and details options \u2014 by supplying attacker-controlled gallery IDs. The nonce bypass requires omitting the nonce POST field entirely rather than submitting an invalid value, as a present-but-invalid nonce is correctly rejected."}], "lastModified": "2026-09-18T15:17:17.990", "sourceIdentifier": "security@wordfence.com"}
