CVE-2026-16292: CWE-352 Cross-Site Request Forgery (CSRF) in Frontend File Manager Plugin
The Frontend File Manager Plugin for WordPress through version 23.6 contains a Cross-Site Request Forgery (CSRF) vulnerability due to missing nonce validation on a file-metadata update action. This flaw allows an attacker to modify metadata of files uploaded by logged-in users via a CSRF attack, potentially enabling unauthorized file downloads. If guest uploads are enabled, the vulnerability can be exploited without authentication against any user's files.
AI Analysis
Technical Summary
CVE-2026-16292 is a CSRF vulnerability in the Frontend File Manager Plugin for WordPress (up to version 23.6) caused by the absence of nonce validation on a file-metadata update action. This allows attackers to perform unauthorized modifications to file metadata of logged-in users through crafted requests. When guest uploads are enabled, the vulnerability extends to unauthenticated attackers targeting any user's files. No official patch or remediation guidance is currently available.
Potential Impact
An attacker can exploit this vulnerability to modify metadata of files uploaded by authenticated users, which can be leveraged to download those files without proper authorization. The risk increases if guest uploads are enabled, as unauthenticated attackers can exploit the vulnerability against any user's files. This could lead to unauthorized access and potential data leakage.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider disabling guest uploads if enabled to reduce the attack surface. Monitor for updates from the plugin vendor regarding patches or official mitigations.
