Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete tenant context validation and lack of context cleanup can allow tenant IDs to leak across execution threads, leading to severe cross-tenant data access bypasses.
Deserialization of Untrusted Data: Using standard Java native serialization on Redis backends opens up the platform to remote code execution (RCE) via untrusted serialized payloads.
Auth Bypass: Using 'get' instead of 'delete' for client details cache eviction fails to invalidate active sessions, leaving revoked or modified clients authorized.
