{"id":"CVE-2026-2899","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-2899","generatedAt":"2026-10-27T23:56:25.575Z","title":"The Fluent Forms Pro Add On Pack plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 6.1.17.","description":"The Fluent Forms Pro Add On Pack plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 6.1.17. This is due to the `deleteFile()` method in the `Uploader` class lacking nonce verification and capability checks. The AJAX action is registered via `addPublicAjaxAction()` which creates both `wp_ajax_` and `wp_ajax_nopriv_` hooks. This makes it possible for unauthenticated attackers to delete arbitrary WordPress media attachments via the `attachment_id` parameter.\r\n\r\nNote: The researcher described file deletion via the `path` parameter using `sanitize_file_name()`, but the actual code uses `Protector::decrypt()` for path-based deletion which prevents exploitation. The vulnerability is exploitable via the `attachment_id` parameter instead.","published":"2026-03-05T04:15:57.000Z","lastModified":"2026-06-17T10:32:00.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00236,"percentile":0.14513,"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":"low","text":"Lower severity and a low EPSS score (0.24%).
