CVE-2025-61768Public exploitNetwork attack vector

Authenticated SSRF via external SVG image references

Published Oct 6, 2025 · Updated Oct 6, 2025

SSRF in the KUNO CMS Media module before 1.3.15 allows remote authenticated users to probe internal networks through crafted SVG uploads. The SVG processor follows unvalidated xlink:href image references and makes HTTP requests to attacker-selected external domains or internal IP addresses. Administrative-panel access is required; successful exploitation exposes reachable internal services and response-derived information and can consume server resources.
