Location-data disclosure via unchecked WebSocket origin
Published Feb 23, 2026 · Updated Feb 23, 2026
Cross-site WebSocket hijacking in Traccar Server 6.11.1 and earlier allows remote attackers to read live location data via /api/socket. The WebSocket handshake accepts an arbitrary or null Origin header and upgrades the connection while the browser supplies the victim's JSESSIONID cookie. A victim must be logged in and visit an attacker-controlled site; the resulting stream exposes positions, device identifiers, protocols, and battery levels.
