Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Attackers can bypass internode authentication via malformed URL paths or incorrect signature validation states, leading to complete cluster takeover. Explicit cryptographic signature verification and early filter rejection are mandatory.

Remote Code Execution: Executing untrusted configsets allows the loading of arbitrary Java classes or malicious script code. Untrusted configsets must be restricted from using dynamic file execution libraries or registering custom listeners.

Path Traversal: Insufficient validation of file names and paths during configset zip uploads allows attackers to write arbitrary files or overwrite sensitive configurations in ZooKeeper and local file systems.
