CVE-2026-76124

8.8 high

High (8.8).

The BuddyBoss App plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.2.1 via the send_feedback function. This is due to insufficient file type validation that relies solely on the client-supplied Content-Type header without server-side content inspection or extension validation. 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. While uploaded files are deleted after email transmission, a race condition exists during SMTP execution that allows access to the file, and files persist indefinitely when wp_mail() fails.
