CVE-2026-43980
malla: Stored XSS via Meshtastic node names in multiple frontend pages
描述
Node names (long_name, short_name) received via MQTT are stored in SQLite without sanitization and rendered into the DOM without escaping. Any participant on a public Meshtastic MQTT broker can set a malicious node name that executes JavaScript in the browser of every Malla dashboard visitor. Affected files: - src/malla/templates/traceroute_graph.html (line ~832) - src/malla/templates/map.html (lines ~945, 1078) - src/malla/templates/packet_detail.html (lines ~1402, 1452) - src/malla/static/js/relay_node_analysis.js (line ~124) Steps to reproduce 1. Publish a Meshtastic NODEINFO_APP packet to any public MQTT broker with long_name set to a HTML entity i.e `<img src=x onerror=alert(1)>` 2. Wait for malla-capture to store it 3. Open the dashboard Impact Allows unauthenticated remote attackers to execute arbitrary JavaScript in the browser, such as: - Phishing overlays - Force redirect to malicious websites - Injection of arbitrary third-party scripts (no CSP restrictions) - Browser resource abuse - Persistent dashboard denial of service
