What happened

MyTube is a self-hosted downloader and player for several video websites. Prior to version 1.10.3, backend video access does not enforce the visitor role's intended public-only restriction when loginEnabled=true and a visitor password is configured. The frontend filter in VideoContext.tsx is only client-side, roleBasedAuthMiddleware.ts allows all visitor GET requests, and storageService/videos.

ts performs getVideos() and getVideoById(id) queries without checking the caller's role or visibility. A visitor can enumerate /api/videos or request /api/videos/:id to retrieve hidden visibility=0 records, exposing titles, sourceUrl values, videoPath values, subtitle paths and thumbnailPath values. The serveMountVideo() path also serves mounted video files without visibility checks.

Leaked paths work against unauthenticated /videos/* and /subtitles/* routes, allowing media downloads without credentials. The RSS visitor feed already filters visibility=1 content and is not the affected query path. Default loginEnabled=false single-user deployments are unaffected by this role-boundary issue because all callers are owner-equivalent. This issue is fixed in version 1.10.3.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 21:20 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
