Unrestricted file upload in HUMANIST 26.0 allows remote attackers to execute code by placing a web shell on the server. The Turkish national advisory does not identify the upload endpoint or disclose which file-type validation operation fails. No credentials or user interaction are required; a successful upload grants code execution in the web server's security context.
