CVE-2026-40348Public exploitNetwork attack vector

Authenticated SSRF via unrestricted Jellyfin URL verification

Published Apr 18, 2026 · Updated Apr 18, 2026

SSRF in Movary before 0.71.1 allows remote authenticated users to probe internal services through Jellyfin URL verification. The endpoint appends /system/info/public to an untrusted base URL and passes it to Guzzle without blocking loopback, private, or internal DNS targets. Any ordinary account can distinguish reachable services, missing resources, and closed ports through response differences, enabling internal host, port, and service discovery.
