Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The application historically used substring or pattern-matching comparisons for role and permission strings instead of exact matches, enabling unintended privilege escalation. Developers must enforce strict equality checks.
Deserialization: Untrusted data deserialization through Redis serialization layers with open auto-type settings can lead to remote code execution. A strict package whitelist must always be enforced.
Path Traversal: Accepting user-controlled file names directly to the file transfer interface permits directory traversal attacks. Utilizing random UUID file-naming policies mitigates this risk.
