Technical details

The SigmaForms Pro plugin for WordPress is vulnerable to an unrestricted arbitrary file upload (CWE-434) in versions up to and including 1.4.5. The vulnerability allows an unauthenticated remote attacker to upload dangerous file types, such as PHP scripts, to the server. While the CVSS vector indicates high complexity (AC:H), the lack of authentication requirements (PR:N) and the potential for a changed scope (S:C) make this a high-impact flaw. Successful exploitation can lead to full remote code execution (RCE) and complete site compromise. The issue is resolved in version 1.4.6.
