MyTube 1.10.3 以後版本修復未授權媒體存取漏洞（CVE-2026-62302）
CVE-2026-62302 - MyTube: Unauthenticated Media Access via Static Routes Bypassing Login
導語：MyTube 1.10.3 以前的版本存在身份驗證繞過漏洞，攻擊者可直接下載本地或雲端媒體。
- 漏洞細節：
staticRoutes.ts與cloudRoutes.ts在registerApiRoutes前註冊，導致/videos/*、/images/*、/avatars/*等路徑不受身份驗證限制。
MyTube 1.10.3 以後版本已修復身份驗證繞過漏洞，使用者應即時升級以防止未授權媒體存取。
MyTube is a self-hosted downloader and player for several video websites. Prior to version 1.10.3, `server.ts` calls `registerStaticRoutes` and `registerCloudRoutes` before `registerApiRoutes`, where `authMiddleware` and `roleBasedAuthMiddleware` are mounted. Because Express processes middleware in registration order, `staticRoutes.ts` and `cloudRoutes.ts` remain outside the authentication stack even when `loginEnabled=true`. Unauthenticated clients can access local videos through `/videos/*`, thumbnails through `/images/*` and `/images-small/*`, avatars through `/avatars/*`, subtitles through `/subtitles/*`, cloud thumbnail caches through `/api/cloud/thumbnail-cache/*`, and cloud signed URLs or redirects through `/cloud/videos/:filename` and `/cloud/images/:filename`. The frontend login wall does not protect direct media requests. Cloud routes return 404 when cloud storage is unconfigured, but that is not an authentication rejection; protected API routes correctly return 401. Combined with hidden-video path leaks, the flaw permits unauthenticated downloads of hidden media. Default loginEnabled=false single-user deployments have no authentication boundary to bypass. This issue is fixed in version 1.10.3.
