Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Misassignment of a wrapped session request to a local variable instead of the active request parameter allowed filters further down the chain to bypass session-provider security controls entirely. This represents a systemic framework routing risk.
Auth Bypass: Missing redirection logic allowed requests with missing or null sessions to pass through the CheckSession filter, leading to direct access to protected resources without authenticating.
Auth Bypass: Using a single generic key for multiple account types allowed different account roles to clobber and overwrite each other's session state, leading to cross-role privilege escalation.
