Medium severity, CVSS 5.4. EPSS: 0.1% chance of exploitation in the next 30 days.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not perform nonce validation on one of its file-metadata update actions, allowing an attacker to modify the metadata of a logged-in user's uploaded file via a CSRF attack, which can be leveraged to download that file.
