CVE-2026-95679Network attack vector

Unauthenticated blind SSRF via XML URL parsing

Published Sep 22, 2026 · Updated Sep 22, 2026

Blind SSRF in MISP before 2.5.47 allows remote attackers to make arbitrary outbound HTTPS requests through unauthenticated XML posts. The RequestHandlerComponent automatically decodes XML write bodies, and Xml::build() lets bare HTTPS URLs bypass its readFile guard because of operator precedence. Reachability requires the unauthenticated cspReport endpoint and server egress; attackers receive no body but can probe or trigger reachable HTTPS services.
