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.","severity":{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00437,"percentile":0.38277,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-434"],"published":"2026-11-03T12:31:54Z","modified":"2026-11-03T15:32:00Z","products":[{"vendor":"buddyboss","product":"buddyboss app"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/56a1219c-1163-4867-b426-7ffe9ca5dcb5?source=cve"},{"url":"https://buddyboss.com/resources/buddyboss-app-plugin-releases/3-2-2/"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76124"},{"url":"https://buddyboss.com/resources/buddyboss-app-plugin-releases/3-2-2"},{"url":"https://github.com/advisories/GHSA-qj2m-6jmm-rjxw"}],"sources":{"cve":[{"id":"CVE-2026-76124","title":"BuddyBoss App \u003c= 3.2.1 - Authenticated (Subscriber+) Arbitrary File Upload via Feedback Endpoint","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.
