CVE-2026-62345: Wanderer stored cross-site scripting in waypoint icon

CVE-2026-62345 · Severity: high · CVSS 7.6 · Published 2026-11-06

Wanderer is a self-hosted trail database for recording and sharing outdoor adventures. An authenticated user can craft a malicious waypoint icon value that executes JavaScript when another user views the affected trail map, potentially exposing session tokens or allowing the attacker to perform actions as the victim. Waypoint data can also reach this vulnerability when federated between instances without requiring a local account.

Technical details

This is a stored cross-site scripting (XSS) vulnerability in the createMarkerFromWaypoint() function, which passes an unvalidated waypoint.icon value to FontawesomeMarker using insertAdjacentHTML, allowing arbitrary HTML and script injection. An authenticated attacker can store a crafted waypoint.icon payload that executes in the browser of any user viewing the map. The vulnerability also affects federated waypoint data, which can reach the vulnerable code path without the receiving instance requiring authentication.
