Frontend File Manager Plugin
Monthly
Unauthenticated file disclosure in the Frontend File Manager Plugin for WordPress (all versions through 23.6) exposes every user-uploaded file to anonymous download via identifier enumeration. The plugin's file download handler fails to properly enforce WordPress nonce validation, stripping the only access control gate between unauthenticated HTTP requests and user-uploaded content. A public proof-of-concept is available via WPScan, and SSVC assessment confirms the attack is automatable - any script that iterates numeric file identifiers can bulk-harvest uploaded documents, images, or sensitive attachments without credentials. Not currently listed in CISA KEV.
Cross-site request forgery in the Frontend File Manager Plugin for WordPress (all versions through 23.6) enables attackers to silently modify file metadata belonging to authenticated users by luring victims to attacker-controlled pages, with the corrupted metadata directly enabling unauthorized download of those files. When the plugin's guest upload feature is active, the vulnerable metadata update endpoint becomes fully unauthenticated, eliminating the need for any victim interaction and exposing every user's uploaded files to arbitrary metadata manipulation. WPScan has published a proof-of-concept, though EPSS at 0.10% (1st percentile) indicates limited observed exploitation activity to date - no public exploit identified at time of analysis reaches CISA KEV status.
Permanent deletion of arbitrary WordPress posts and pages is possible via the Frontend File Manager Plugin (all versions through 23.6), which omits ownership verification before executing delete operations. Any authenticated user holding author-level access or higher can permanently destroy content they do not own; when an administrator enables the 'Allow guest uploads' setting, the same endpoint becomes reachable by completely unauthenticated users. A public proof-of-concept exists via WPScan; no confirmed actively exploited status (KEV), and EPSS sits at just 0.18% (8th percentile), but the unauthenticated attack path under a non-default configuration is the highest-severity scenario.
Stored Cross-Site Scripting in the Frontend File Manager Plugin for WordPress (versions through 23.6) allows any authenticated subscriber-level user to compromise administrator sessions by injecting malicious script payloads via the frontend file-rename endpoint. The unsanitized filename is persisted as post meta and subsequently rendered unescaped within the WordPress admin File Manager listing, triggering execution whenever an administrator views that interface. A publicly available proof-of-concept exists per WPScan, and no confirmed patched version is identified in available data, making this an unresolved risk for all sites running this plugin at or below version 23.6.
Frontend File Manager Plugin for WordPress through version 23.6 allows authenticated Subscriber-level users and higher to read arbitrary files belonging to other users via insecure direct object reference (IDOR) in the download endpoint. By manipulating the 'file_id' parameter, attackers can bypass authorization checks and access sensitive data stored by administrators and other privileged users. Publicly available exploit code exists for this vulnerability, though EPSS scoring (0.02%) suggests limited real-world exploitation relative to its high CVSS rating.
The Frontend File Manager Plugin WordPress plugin before 22.6 has a vulnerability that allows an Editor+ user to bypass the file download logic and download files such as `wp-config.php`. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
