Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Using mismatching path matchers between Spring Security and Spring MVC allows attackers to bypass access rules via subtle path variations. Migrating to MvcRequestMatcher addresses this mismatch.
Auth Bypass: Improperly split HttpSecurity configuration blocks can lead to unauthenticated resource server endpoints. Consolidating security configurations ensures uniform enforcement.
Auth Bypass: Null or empty role vectors passed to database queries can result in unrestricted querying of resources if not explicitly guarded. Returning an empty set early mitigates this.
