Description
Bludit CMS before version 3.18.4 allows Remote Code Execution (RCE) via the API Plugin. The POST /api/files/{key} endpoint in bl-plugins/api/plugin.php fails to perform authorization checks and lacks file extension validation. An attacker with a valid API token can upload a malicious PHP script and execute arbitrary code on the server.
