CVE-2025-53457Network attack vector

Administrator-triggered internal requests via unrestricted backlink checks

Published Sep 22, 2025 · Updated Apr 28, 2026

SSRF in Active Websight SEO Backlink Monitor 1.8.0 and earlier allows remote authenticated users to send requests to arbitrary URLs. The backlink-check workflow passes an administrator-supplied link to the server's HTTP request path without restricting internal or arbitrary destinations; public advisories do not name the vulnerable function. Administrator access is required, and successful exploitation can disclose or modify data exposed by reachable internal services.
