Vulnerability details
The vulnerability allows a remote attacker to disclose stream keys and direct HLS URLs and view currently live unlisted, private, or group-restricted streams without authorization.
The vulnerability exists due to missing authentication and failure to redact sensitive fields in AVideo's plugin/Live/stats.json.php when returning statistics with the Live plugin enabled, retaining restricted streams' keys and m3u8 URLs in hidden_applications entries. A remote attacker can send GET /plugin/Live/stats.json.php without cookies and extract these entries to access restricted streams.
