CVE-2025-57814Public exploitNetwork attack vector

SSRF via skipped HTTPS direct-IP validation

Published Aug 25, 2025 · Updated Aug 26, 2025

SSRF in request-filtering-agent before 2.0.0 allows remote attackers to access localhost HTTPS services through user-controlled URLs. During TLS setup, RequestFilteringHttpsAgent fails to invoke the connection listener that validates direct IP addresses, so 127.0.0.1 is treated as safe. Exploitation requires an application to accept attacker-controlled URLs and use the library for requests to a localhost HTTPS service.
