WWBN AVideo through 30.0 (and master up to commit 4cb576e) contains a cross-site request forgery vulnerability in plugin/Live/myLiveControls.save.json.php. The endpoint only checks that a user is logged in and processes customUrl, customMessage, and autoRedirect parameters from $_REQUEST via a GET request without enforcing a CSRF token or origin check. An attacker who lures a logged-in streamer to a malicious page can silently change the live-channel viewer-redirect settings (persisted in users.externalOptions), causing viewers to be redirected to a phishing site or shown a spoofed message.

Cross-site request forgery in AVideo's live-channel controls endpoint allows a remote, unauthenticated attacker to silently hijack a logged-in streamer's viewer-redirect configuration. The PHP endpoint /plugin/Live/myLiveControls.save.json.php accepts GET requests without a CSRF token or origin check, permitting an attacker who can socially engineer a streamer to visit a malicious page to overwrite customUrl, customMessage, and autoRedirect settings persisted in users.externalOptions. …
