AVideo has CORS Origin Reflection Bypass via plugin/API/router.php and allowOrigin(true) that Exposes Authenticated API Responses

WWBN AVideo is an open source video platform. In versions 29.0 and below, the CORS origin validation fix in commit `986e64aad` is incomplete. Two separate code paths still reflect arbitrary `Origin` headers with credentials allowed for all `/api/*` endpoints: (1) `plugin/API/router.php` lines 4-8 unconditionally reflect any origin before application code runs, and (2) `allowOrigin(true)` called by `get.json.php` and `set.json.php` reflects any origin with `Access-Control-Allow-Credentials: true`. An attacker can make cross-origin credentialed requests to any API endpoint and read authenticated responses containing user PII, email, admin status, and session-sensitive data. Commit 5e2b897ccac61eb6daca2dee4a6be3c4c2d93e13 contains a fix.

源验证错误

WWBN AVideo 访问控制错误漏洞

WWBN AVideo是WWBN团队的一个由PHP编写的视频平台建站系统。 WWBN AVideo 29.0及之前版本存在访问控制错误漏洞，该漏洞源于CORS来源验证修复不完整，两个代码路径仍反射任意Origin标头，可能导致攻击者对任何API端点进行跨域凭据请求，读取包含用户PII的认证响应。
