45th percentile - higher than 45% of all known CVEs

Summary

The FS-Poster plugin for WordPress is vulnerable to Remote Code Execution in versions up to and including 8.0.1. This is due to insufficient input sanitization of the FFmpeg path parameter before passing it to the exec() function, combined with missing authorization checks on the REST API endpoints. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary commands on the underlying server.

Risk Assessment

An attacker with low privileges can execute arbitrary commands on the server, potentially leading to full compromise of the site and server.

Recommendation

Update the FS-Poster plugin to the latest version that includes the fix and restrict REST API access to trusted users only.
