CVE-2026-62346

Wanderer: Stored XSS via waypoint.name and waypoint.icon in Elevation Profile innerHTML

Published Nov 6, 2026 CVSS 3.1 · 7.6 High EPSS < 1% KEV · Not listed
Description
Wanderer is a self-hosted trail database for saving and sharing adventures. Prior to 0.19.3, an authenticated local user can submit crafted waypoint.name and waypoint.icon values that the trail elevation graph interpolates into an innerHTML template in web/src/lib/vendor/maplibre-elevation-profile/elevationprofile.ts without HTML encoding or icon validation. A victim viewing the elevation profile executes the attacker-controlled script in their browser. Separately, federated waypoints can deliver the same malicious fields across instances without requiring the attacker to have a local account on the receiving instance. The script can expose session data or perform actions in the victim's context. This issue is fixed in version 0.19.3.
