Overview
About vulnerability
Spring Authorization Server Dynamic Client Registration endpoints perform insufficient validation of certain client metadata fields when explicitly enabled.
An attacker possessing a valid Initial Access Token can dynamically register a malicious client with crafted metadata. Depending on the metadata provided and the Authorization Server’s configuration, this can lead to Stored Cross-Site Scripting (XSS), Privilege Escalation, or Server-Side Request Forgery (SSRF).
