CVE-2026-89413

Filter Gallery <= 1.1.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Gallery Deletion via 'ufg_gallery_id' Parameter

Published Sep 18, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
The Filter Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.4. 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 — including all associated filters, image mappings, settings, and details options — 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.
