SSRF (Server-Side Request Forgery) in WWBN/AVideo (CVE-2026-39368)
Summary
SSRF in WWBN/AVideo (CVE-2026-39368). Confidential information can be exposed externally. Exploitable via GET /plugin/Live/view/getRestream.json.php.
Original description
The description as published by the source.
Summary
The Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers.
The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.
Details
The vulnerable chain was:
plugin/Live/view/getRestream.json.phpexposed a freshtokenForActionplugin/Live/view/Live_restreams/verifyTokenForAction.json.phpexchanged it for a validresponseTokenplugin/Live/view/Live_restreams_logs/add.json.phpaccepted attacker-controlledrestreamerURLplugin/Live/view/getRestream.json.phpandplugin/Live/view/Live_restreams/getAction.json.phplater fetched that stored URL server-side
The original issue existed because the responseToken was accepted, but the callback destination was not tightly constrained to trusted restreamer endpoints.
The maintainer confirmed the vulnerability and stated that the fix was applied by validating restreamerURL at storage time and re-validating the log-entry branch before use. The maintainer also noted that the m3u8 field follows the same general pattern but is not server-fetched in the current flow.
Proof of concept
- Log in as a non-admin user with streaming permission.
- Create a normal restream destination.
- Trigger `plugin/Live/view/Live_restre…
