Movary has Authenticated SSRF via Jellyfin Server URL Verification that Allows Internal Network Probing

Movary is a self hosted web app to track and rate a user's watched movies. Prior to version 0.71.1, an ordinary authenticated user can trigger server-side requests to arbitrary internal targets through `POST /settings/jellyfin/server-url-verify`. The endpoint accepts a user-controlled URL, appends `/system/info/public`, and sends a server-side HTTP request with Guzzle. Because there is no restriction on internal hosts, loopback addresses, or private network ranges, this can be abused for SSRF and internal network probing. Any ordinary authenticated user can use this endpoint to make the server connect to arbitrary internal targets and distinguish between different network states. This enables SSRF-based internal reconnaissance, including host discovery, port-state probing, and service fingerprinting. In certain deployments, it may also be usable to reach internal administrative services or cloud metadata endpoints that are not directly accessible from the outside. Version 0.71.1 fixes the issue.

服务端请求伪造(SSRF)

Movary 安全漏洞

Movary是Lee Peuker个人开发者的一个影评程序。 Movary 0.71.1之前版本存在安全漏洞，该漏洞源于/settings/jellyfin/server-url-verify端点接受用户控制的URL并发起服务器端HTTP请求，缺少对内部主机、环回地址或私有网络范围的限制，可能导致经过身份验证的普通用户进行SSRF和内部网络探测。
