CVE-2026-45619Network attack vector

Unauthenticated internal network access via unpinned DNS resolution

Published May 29, 2026 · Updated May 29, 2026

SSRF in World Wide Broadcast Network AVideo 29.0 and earlier allows remote attackers to send server-side requests through DNS rebinding. EpgParser.php, plugin/AI/receiveAsync.json.php, and at least six other call sites validate a hostname with isSSRFSafeURL() but discard its resolved IP instead of pinning cURL to it. No authentication or user interaction is required, but exploitation must win the DNS time-of-check/time-of-use race and exposes or modifies resources reachable from the server.
