CWE-285

Description

OpenAM before 16.1.3 applies its OAuth2 Provider PKCE enforcement only to authorization requests whose response_type is exactly code, so codes issued through OpenID Connect hybrid flows (code token, code id_token, code token id_token) carry no bound challenge. An attacker who intercepts such a code can redeem it for a public client's tokens with any non-empty code_verifier.
