Technical details
The vulnerability exists in Mdl_templates.php, which scans a writable template directory and automatically trusts all PHP files found in it for use as public invoice templates. An attacker with admin file-write access can place a malicious PHP file in the template directory; when a guest requests a public invoice, the View controller includes and executes the attacker's file with web-server privileges. The fix (v1.7.2-rc-1) replaces directory scanning with explicit configuration allowlisting.
