Openpanel · Openpanel · CVE-2026-85614
**Name of the Vulnerable Software and Affected Versions**
OpenPanel versions prior to 2.3.0
**Description**
An unauthenticated server-side request forgery (SSRF) exists in the 'GET /tools/site-checker' endpoint. The issue occurs because the endpoint accepts a client-controlled `URL` parameter without implementing private IP filtering or DNS-rebinding protection. This allows attackers to force the server to send requests to internal services, localhost, and cloud metadata endpoints, enabling the retrieval of internal HTTP response titles, headers, status codes, and SSL certificate information.
**Recommendations**
Update to version 2.3.0 or later.
Avoid using the `URL` parameter in the 'GET /tools/site-checker' endpoint until the update is applied.
