CVE-2026-76124: BuddyBoss App arbitrary file upload in send_feedback

CVE-2026-76124 · Severity: high · CVSS 8.8 · Published 2026-11-03

The BuddyBoss App is a WordPress plugin that helps site owners build mobile applications. Authenticated users can upload arbitrary executable files through the send_feedback function due to weak file validation, leading to remote code execution. Although files are normally deleted after email transmission, a race condition and email failures allow attackers to access or retain uploaded files indefinitely.

Vendors: BuddyBoss.

Technical details

The vulnerability exists in the send_feedback function's file upload handling, which validates file types only by checking the client-supplied Content-Type header without server-side inspection or extension validation. Authenticated attackers with subscriber-level access can upload executable files. While uploaded files are typically deleted after SMTP execution, a race condition during email transmission and persistent storage when wp_mail() fails enable arbitrary file access and remote code execution.
