{"id":"CVE-2026-12954","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-12954","generatedAt":"2026-10-27T23:59:23.955Z","title":"The Mapster WP Maps plugin for WordPress is vulnerable to Arbitrary User Meta Write in all versions up to, and including, 1.23.0 via the `my_profile_update()` function.","description":"The Mapster WP Maps plugin for WordPress is vulnerable to Arbitrary User Meta Write in all versions up to, and including, 1.23.0 via the `my_profile_update()` function. This is due to the function performing no nonce verification, no capability check, and no allowlist validation on the meta key supplied via the `acf-photo-gallery-groups` POST parameter before passing both the meta key and its corresponding value directly to `update_user_meta()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary user meta values, though privilege escalation is not possible.","published":"2026-09-18T08:16:59.000Z","lastModified":"2026-09-19T15:16:58.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":[],"epss":{"score":0.00648,"percentile":0.5077,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.65%).
