### Summary The OAuth 2.0 / OpenID Connect authorization endpoint does not sufficiently sanitize certain user-supplied parameters before incorporating them into the HTML response generated for the `form_post` response mode. This may allow an attacker to inject content into the rendered page in the context of the OpenAM origin.
Update org.openidentityplatform.openam:openam-oauth2 to 16.1.1 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in maven. A critical vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
