Summary

The FV Flowplayer Video Player plugin for WordPress through 7.5.54.7212 has incomplete file type validation in check_mimetype (CWE-434). Bypassable extension checks let attacker-supplied remote file content be written without a MIME check or enforced extension. Authenticated attackers with subscriber-level access or above can upload possibly executable files, which may allow remote code execution when the 'profile videos on bio' option is enabled.

Description from the CNA

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Limited Arbitrary File Upload in all versions up to, and including, 7.5.54.7212 via the check_mimetype function. This is due to incomplete file type validation in the check_mimetype function — while some extension checking is present, it can be bypassed, allowing attacker-supplied remote file content to be written with insufficient extension enforcement and no MIME check or WordPress upload helper. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. Exploitation requires the plugin's 'profile videos on bio' option to be enabled, as this causes the nonce to be emitted on the subscriber-accessible profile page; without this setting, authenticated users below Editor cannot obtain the required nonce.
