Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Path Traversal: Insecure handling of the 'fontfile' parameter allowed attackers to traverse directories and load arbitrary files. This risk is particularly severe because the vulnerable sink is shared across multiple web entry points.

Reflected XSS: User-supplied font names were directly reflected in the HTML response without sanitization, exposing users to malicious script execution via crafted URLs.
