CVE-2026-39368Public exploitNetwork attack vector

Internal service access via stored callback URL

Published Apr 7, 2026 · Updated Apr 7, 2026

Stored SSRF in World Wide Broadcast Network AVideo 26.0 and earlier allows remote authenticated users to read internal HTTP responses. The Live restream log flow stores an untrusted restreamerURL and later fetches it without restricting the destination to configured restreamer endpoints. Streaming permission is sufficient to proxy requests to loopback or internal services and return their responses through application endpoints.
