Overview

Affected versions of this package are vulnerable to Incorrect Authorization when the request body exceeds the configured maxBodyBytes limit, resulting in the full payload being forwarded to the upstream service while policy evaluation occurs against an empty parsed_body. An attacker can bypass policy enforcement by sending oversized request bodies that are not properly evaluated by the policy engine.
