{"cve":"CVE-2026-62302","nvd":{"published":"2026-10-30T20:17:12.063","modified":"2026-10-30T20:17:12.063","status":"Received","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-306"],"references":["https://github.com/franklioxygen/MyTube/commit/7cc7c6a7d297ccbd8bd2c76755129381b96f8456","https://github.com/franklioxygen/MyTube/security/advisories/GHSA-rwwf-29mq-5j43","https://github.com/franklioxygen/MyTube/tree/v1.10.3"],"products":[],"source":"nvd","synced_at":"2026-10-30T20:41:38.734504606+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
