Description

The vulnerability allows a remote user to conduct cross-site scripting, escalate privileges, or trigger server-side request forgery.

The vulnerability exists due to improper input validation in dynamic client registration endpoints when processing crafted client metadata fields. A remote user can register a malicious client with crafted metadata to conduct cross-site scripting, escalate privileges, or trigger server-side request forgery.

Only deployments with dynamic client registration explicitly enabled are vulnerable.
