Attackers can craft or enumerate sequential msg_id values and set a global flag in the stream_handler endpoint to route requests through the operator's personal Userbot account, exposing private channels, groups, and Saved Messages, while the unauthenticated thumb_handler endpoint further discloses thumbnails from those same chats without any token validation.\nhttps://www.cve.org/CVERecord?id=CVE-2026-109427https://gist.github.com/mansurmavlankulov/489554cad7b38e07b9651c217f00fffbhttps://www.vulncheck.com/advisories/telegram-stremio-broken-object-authorization-via-stream-ids#weebzone #Telegram-Stremio#CVE_2026_109427#bot", "url": "https://infosec.exchange/users/cve/statuses/117429863778525841"}, {"timestamp": "2026-10-12T21:17:11Z", "date_only": false, "value": "2026-10-12T21:17:11Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-Q45W-888C-VPFR", "record": "GHSA-Q45W-888C-VPFR", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-12T21:17:11.460Z", "date_only": false, "value": "2026-10-12T21:17:11.460", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-109427", "record": "FKIE_CVE-2026-109427", "field": "published"}, {"timestamp": "2026-10-12T21:31:59Z", "date_only": false, "value": "2026-10-12T21:31:59Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-Q45W-888C-VPFR", "record": "GHSA-Q45W-888C-VPFR", "field": "published"}, {"timestamp": "2026-10-12T21:31:59Z", "date_only": false, "value": "2026-10-12T21:31:59Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-Q45W-888C-VPFR", "record": "GHSA-Q45W-888C-VPFR", "field": "modified"}, {"timestamp": "2026-10-16T19:18:44.867Z", "date_only": false, "value": "2026-10-16T19:18:44.867", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-109427", "record": "FKIE_CVE-2026-109427", "field": "lastModified"}]}
