Technical details
The blocklist workflow module accepted unsanitized filename parameters with only basename() filtering and empty/dot checks, failing to validate file extensions. An authenticated site administrator can trigger the workflow with a crafted filename containing a script extension (e.g., .php), placing an executable file in the web-accessible export directory. This leads to arbitrary code execution if the web server is configured to interpret scripts in that location.
