CVE-2026-76124 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.8 (high) and affects BuddyBoss App; no fixed version is listed yet.

## Summary

The BuddyBoss App plugin for WordPress is affected, allowing any logged-in user with subscriber-level access or higher to upload files through its feedback feature. Because file type checks rely only on the client-supplied content type, attackers could upload executable files, potentially leading to remote code execution on the affected site.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- BuddyBoss BuddyBoss App: through 3.2.1

## 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.
