The issue occurs when a user with the view-clients role accesses the client registration endpoint to retrieve client details. Due to a failure to mask sensitive information, the service returns the client's confidential secret in cleartext. This could allow a read-only administrator to obtain full access to the affected client's account and potentially escalate their privileges within the realm.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":27,"depthScoreParts":{"impact":27,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
