Overview

Affected versions of this package are vulnerable to Incorrect Implementation of Authentication Algorithm due to the too broad path-template matching in the runtime authentication layer. An attacker can cause sensitive authentication credentials to be sent to unintended endpoints that may result in disclosure of bearer tokens, API keys, or basic credentials to lower-trust routes, and allow public operations to be invoked with privileged credentials.
