Recurring patterns

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

Cross-Site Request Forgery (CSRF): A vulnerability in origin validation (CWE-200) allows remote attackers to bypass the Same Origin Policy and leak CSRF tokens to third-party domains when a URL contains a leading space, enabling cross-site request forgery attacks.

Reflected XSS: The HTML prefilter logic inside the vendored jQuery library (specifically handling self-closing tag expansion) can be abused to execute arbitrary JavaScript within the context of the user's session if untrusted HTML is passed to jQuery DOM manipulation methods.

Insecure Transport: The build-time task used to fetch vendored assets was historically configured to download jQuery over unencrypted HTTP, exposing developers and users to Man-in-the-Middle (MitM) attacks where the downloaded JavaScript could be silently tampered with.
