{"id":"CVE-2026-6566","state":"PUBLISHED","title":"Photo Gallery, Sliders, Proofing and Themes <= 4.2.0 - Insecure Direct Object Reference to Authenticated (Subscriber+) Image Deletion via REST API","description":"The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0. This is due to insufficient object-level authorization in the image deletion REST flow where the permission callback for DELETE /imagely/v1/images/{id} only checks 'NextGEN Manage gallery' permissions and does not enforce gallery ownership or 'NextGEN Manage others gallery' permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and 'NextGEN Manage gallery' capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default).","publishedAt":"2026-05-20T05:31:10.536Z","updatedAt":"2026-05-20T15:54:05.752Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["smub Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery"],"affected":[{"vendor":"smub","product":"Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.2.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/439809ad-21ea-4a0b-b1fd-5de9f8f5ee7a?source=cve","https://plugins.trac.wordpress.org/changeset/3533432/nextgen-gallery"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6566.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6566","state":"PUBLISHED","datePublished":"2026-05-20T05:31:10.536Z","dateUpdated":"2026-05-20T15:54:05.752Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-18T17:51:56.808Z"},"containers":{"cna":{"title":"Photo Gallery, Sliders, Proofing and Themes <= 4.2.0 - Insecure Direct Object Reference to Authenticated (Subscriber+) Image Deletion via REST API","descriptions":[{"lang":"en","value":"The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0.
