{"affected":[{"product":"MyTube","source":"CNA: GitHub_M","vendor":"franklioxygen","versions":[{"status":"affected","version":"< 1.10.6"}]}],"cveId":"CVE-2026-63434","cwes":["CWE-20"],"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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":4.3,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"}],"modifiedAt":1793735464967,"publishedAt":1793735464967,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/franklioxygen/MyTube/security/advisories/GHSA-h5xx-g8fc-crr7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/franklioxygen/MyTube/commit/5cfbc22166de64dfb65cb789ef00909dd48783d7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/franklioxygen/MyTube/commit/60424529121018cbf0481034a97fca36d3bc5c66"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/franklioxygen/MyTube/commit/d65913a9319dd840ab2ac77565325cf701306d6d"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/franklioxygen/MyTube/releases/tag/v1.10.6"}],"remediation":[],"revision":"d5f61b43107032ac92fcc3f84bed995c635d672172f5016fe47eba8bea7073bf","sources":[{"modifiedAt":1793735464967,"name":"CNA: GitHub_M","retrievedAt":1793736594877,"url":"https://www.cve.org/CVERecord?id=CVE-2026-63434"}],"ssvc":null,"status":"published","title":"MyTube: Visitor-Role Statistics Event Forgery Allows Analytics Data Poisoning","updatedAt":1793736594877}
