CVE-2026-73160Network attack vectorHinoki check available

Unauthenticated SSRF via unresolved hostname validation

Published Aug 11, 2026 · Updated Aug 11, 2026

SSRF in MISP Project CTI-Transmute 1.4.0 and earlier allows remote attackers to read internal HTTP responses via crafted hostnames. The _validate_misp_url routine accepted domain names without resolving them, allowing both MISP routes to request private addresses. No login was required, so an anonymous network caller could direct the service to an internal host and receive its response.
