{"id":"CVE-2026-89413","state":"PUBLISHED","title":"Filter Gallery <= 1.1.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Gallery Deletion via 'ufg_gallery_id' Parameter","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.","publishedAt":"2026-09-18T06:38:51.386Z","updatedAt":"2026-09-18T14:31:44.393Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["farazfrank Filter Gallery"],"affected":[{"vendor":"farazfrank","product":"Filter Gallery","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0487c6dd-7453-4473-9a13-6b699623f8a9?source=cve","https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1112","https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1099","https://plugins.trac.wordpress.org/browser/filter-gallery/tags/1.1.4/filter-gallery.php#L1131","https://plugins.trac.wordpress.org/changeset?reponame=&old=3695415%40filter-gallery&new=3695415%40filter-gallery"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/89xxx/CVE-2026-89413.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-89413","state":"PUBLISHED","datePublished":"2026-09-18T06:38:51.386Z","dateUpdated":"2026-09-18T14:31:44.393Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-11T17:08:50.541Z"},"containers":{"cna":{"title":"Filter Gallery <= 1.1.4 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Gallery Deletion via 'ufg_gallery_id' Parameter","descriptions":[{"lang":"en","value":"The Filter Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.4.
