Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
CSRF: Misconfigured route middleware can accidentally exempt critical broadcasting authentication endpoints from CSRF/Request Forgery protections, allowing malicious external sites to register or authenticate to channels on behalf of users.
Auth Bypass: Improper parsing of channel name prefixes prior to access control verification can cause channel authentication checks to evaluate incorrect strings, resulting in unauthorized users gaining access to restricted subscription channels.
