Detailsinfo

A vulnerability was found in franklioxygen MyTube up to 1.10.5 and classified as problematic. This issue affects the function ingestEvents of the file backend/src/controllers/statisticsController.ts of the component Statistics Ingestion. The manipulation of the argument platform/sourceKind/sessionId with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is integrity. The summary by CVE is:

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.
