Summary
MyTube, a self-hosted video downloader and player, is affected when its optional visitor activity statistics are enabled. A visitor-role user can submit fabricated analytics events that falsely attribute platforms, sources, and sessions, which corrupts the view counts, download counts, and other analytics that administrators rely on.
Read the original description
MyTube is a self-hosted downloader and player for several video websites. Prior to 1.10.6, when statisticsEnabled and statisticsTrackVisitorActivity are enabled, a visitor-role user can submit events to the statistics ingest endpoint handled by ingestEvents in backend/src/controllers/statisticsController.ts. The handler reads req.body.events and accepts the client-controlled platform, sourceKind, and sessionId fields without server-side derivation or validation before passing the events to the analytics persistence path. A visitor can therefore attribute fabricated events to arbitrary platforms, sources, and sessions, corrupting administrator-visible view counts, download counts, platform breakdowns, source attribution, and session analytics. The server-derived actorRole and surface fields are not forgeable through this issue. This issue is fixed in version 1.10.6.
What to do
Upgrade to a fixed version: 1.10.6.
