{“lastseen”:””,”description”:”The Photo Gallery, Sliders, Proofing and Themes \u2013 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).”,”published”:”2026-05-20T05:31:10.536Z”,”modified”:”2026-05-20T05:31:10.536Z”,”type”:”cve”,”title”:”Photo Gallery, Sliders, Proofing and Themes \\u003c= 4.2.0 – Insecure Direct Object Reference to Authenticated (Subscriber+) Image Deletion via REST API”,”source”:”Wordfence”,”references”:”https:\/\/www.wordfence.com\/threat-intel\/vulnerabilities\/id\/439809ad-21ea-4a0b-b1fd-5de9f8f5ee7a?source=cve\\nhttps:\/\/plugins.trac.wordpress.org\/changeset\/3533432\/nextgen-gallery”,”id”:”CVE-2026-6566″,”bulletinFamily”:””,”cwe”:[“CWE-639″],”cvelist”:null,”sourceData”:”smub Photo Gallery, Sliders, Proofing and Themes \u2013 NextGEN Gallery 0″,”sourceHref”:””,”cvss”:{“score”:4.3,”severity”:”MEDIUM”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:L\/UI:N\/S:U\/C:N\/I:L\/A:N”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Photo Gallery, Sliders, Proofing and Themes \u2013 NextGEN Gallery”,”version”:”0″,”vendor”:”smub”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
