CVE-2026-76124 Details
Description
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.
A vulnerability allowing arbitrary file upload has been identified in the BuddyBoss App plugin for WordPress, affecting all versions through 3.2.1. The issue arises in the send_feedback function, where file type validation is inadequate, relying only on the client's Content-Type header without proper server-side inspection or extension checks. This flaw enables authenticated attackers with subscriber-level access or higher to upload potentially executable files, leading to remote code execution. Although uploaded files are removed after being sent via email, a race condition during the SMTP process allows access to these files. Furthermore, if the wp_mail() function fails, the files remain on the server indefinitely.
Users are advised to update the BuddyBoss App plugin to version 3.2.2 or a newer patched version.
