Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenAM's openam-oauth2 Maven package, versions before 16.1.1, has an authorization bypass in its stateful OAuth2 token-read path, where caller-supplied identifiers are read from the shared Core Token Store without checking the token type. An attacker who can place attacker-controlled data into the token store under an identifier they know, such as through a Push Notification callback in a Push-enabled realm, can forge OAuth2 bearer and OIDC ID tokens with chosen subject, client, realm, and scope. Upgrade to version 16.1.1.
