Prior to version 4.9.6, Admin-configured OIDC token_url and user_info_url in includes/oidc/handle_oidc_callback.php:18-49 are used directly in curl_init() with zero SSRF filtering. Unlike logo/webhook URLs which have validate_webhook_url_for_ssrf(), OIDC URLs bypass all protections. Admin sets URL to http://169.254.169.254/latest/meta-data/ for cloud metadata access or internal network pivoting. This issue has been patched in version 4.9.6.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
