Postiz: Unauthenticated Full-Read SSRF via /public/stream Endpoint with Trivially Bypassable Extension Check

Postiz is an AI social media scheduling tool. Prior to version 2.21.3, the GET /public/stream endpoint in PublicController accepts a user-supplied url query parameter and proxies the full HTTP response back to the caller. The only validation is url.endsWith('mp4'), which is trivially bypassable by appending .mp4 as a query parameter value or URL fragment. The endpoint requires no authentication and has no SSRF protections, allowing an unauthenticated attacker to read responses from internal services, cloud metadata endpoints, and other network-internal resources. This issue has been patched in version 2.21.3.

Gitroom Postiz 代码问题漏洞

Gitroom Postiz是Gitroom开源的一个社交媒体日程安排工具。 Gitroom Postiz 2.21.3之前版本存在代码问题漏洞，该漏洞源于GET /public/stream端点缺少身份验证和服务端请求伪造保护，可能导致未经身份验证的攻击者读取内部服务的响应。
