CVE-2026-56345— AVideo - Arbitrary User Session Hijacking via Meet Plugin uploadRecordedVideo Endpoint

AVideo - Arbitrary User Session Hijacking via Meet Plugin uploadRecordedVideo Endpoint

AVideo through 29.0 contains an authorization bypass vulnerability in the Meet plugin's uploadRecordedVideo.json.php endpoint that derives the target users_id from the uploaded filename without verification. An attacker with knowledge of the Meet shared secret can craft a malicious file upload with a filename containing an arbitrary users_id to invoke passwordless User->login() and establish an authenticated session as any user including admin. Attackers can obtain the Meet shared secret through path-traversal vulnerabilities or timing attacks against checkToken.json.php, then POST a crafted file to uploadRecordedVideo.json.php with a filename like '1-anything.mp4' to hijack admin sessions and gain full account takeover.

认证机制不恰当

WWBN AVideo 授权问题漏洞

WWBN avideo是WWBN组织开源的一套视频内容管理系统。 WWBN AVideo 29.0及之前版本存在授权问题漏洞，该漏洞源于Meet插件中uploadRecordedVideo.json.php端点从上传文件名中提取目标users_id而未经验证，可能导致攻击者利用已知的Meet共享密钥，通过路径遍历或timing攻击获取共享密钥后，构造包含任意users_id的文件名上传，调用无密码User->login()建立已认证会话，进而劫持管理员会话并完全接管账户。
