Overview
Affected versions of this package are vulnerable to Improper Authorization in the token endpoint when the codeVerifierEnforced setting is disabled. An attacker can obtain access tokens without providing the required PKCE code verifier by intercepting an authorization code and redeeming it without the verifier parameter. This is only exploitable if the codeVerifierEnforced setting is not enabled.
