CVE-2024-50473Network attack vector

Unauthenticated web-shell upload via missing type validation

Published Oct 29, 2024 · Updated May 12, 2026

Unrestricted file upload in Ajar Productions Ajar in5 Embed 3.1.3 and earlier allows remote attackers to place web shells on servers. The unauthenticated admin-ajax.php upload path accepts files[] and customPath data without enforcing safe file types before storing the content. No account or user interaction is required; a server-executable upload grants persistent remote command execution under the web server account.
