Overview

Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel in the EthereumAuthenticator process. An attacker can gain unauthorized access to protected resources by crafting a request path that includes the configured login path as a later segment. This is only exploitable if the protected resource path contains the configured login path as a subsequent segment; explicitly forbidden routes are not affected.
