In versions prior to 16.0.0, if the &#8220;claims_parameter_supported&#8221; parameter is activated, it is possible, thanks to the &#8220;oidc-claims-extension.groovy&#8221; script, to inject the value of one&#8217;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 &#8220;id_token&#8221; and &#8220;user_info&#8221; 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.<\/p>\n<p>Severity: 8.1 | HIGH<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-64099 Published : Nov. 12, 2025, 7:15 p.m. | 17\u00a0minutes ago Description : Open Access Management (OpenAM) is an access management solution.
