Recurring patterns

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

Auth Bypass: Bypassing exact host matches allowed credentials for GitHub.com to be leaked to untrusted subdomains via a loose suffix wildcard. Strict host matching must be enforced for all target URIs.

SSRF: Allowing arbitrary target URIs during authentication validation requests enabled SSRF and credential redirection. Authority endpoints must use hardcoded, validated base URLs.

Auth Bypass: A logical inversion in the credential cache validation logic blocked retrieving secrets from the persistent store when the memory cache was empty, breaking authentication integrity.
