{"id":"CVE-2026-2899","state":"PUBLISHED","title":"Fluent Forms Pro Add On Pack <= 6.1.17 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion","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.","publishedAt":"2026-03-05T03:23:41.411Z","updatedAt":"2026-04-08T17:18:22.782Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","source":"Wordfence"},"assigner":"Wordfence","products":["techjewel Fluent Forms Pro Add On Pack"],"affected":[{"vendor":"techjewel","product":"Fluent Forms Pro Add On Pack","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.1.17","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bb036338-abd7-4061-835d-038b765c68a6?source=cve","https://fluentforms.com/docs/changelog/#3-toc-title"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2899.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2899","state":"PUBLISHED","datePublished":"2026-03-05T03:23:41.411Z","dateUpdated":"2026-04-08T17:18:22.782Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-20T19:07:46.936Z"},"containers":{"cna":{"title":"Fluent Forms Pro Add On Pack <= 6.1.17 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion","descriptions":[{"lang":"en","value":"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.
