CVE ID : CVE-2026-2899
Published : March 5, 2026, 4:15 a.m. | 1 hour, 41 minutes ago
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. Note: 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.
Severity: 6.5 | MEDIUM
