Open Access Management (OpenAM) is an access management solution. In versions prior to 16.0.0, if the "claims_parameter_supported" parameter is activated, it is possible, thanks to the "oidc-claims-extension.groovy" script, to inject the value of one's choice into a claim contained in the id_token or in the user_info. In the request of an authorize function, a claims parameter containing a JSON file can be injected. This JSON file allows attackers to customize the claims returned by the "id_token" and "user_info" files. This allows for a very wide range of vulnerabilities depending on how clients use claims. For example, if some clients rely on an email field to identify a user, an attacker can choose the email address they want, and therefore assume any identity they choose. Version 16.0.0 fixes the issue.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
