Short explanation
Before version 0.19.3, an authenticated user can store a crafted waypoint.icon value; createMarkerFromWaypoint() passes it to FontawesomeMarker, which inserts the unvalidated value via insertAdjacentHTML. When the map is opened, the attacker‑controlled script runs in the viewer’s browser and can steal session tokens. The issue is fixed in version 0.19.3, but official patch status is not verified (S0).
A script running in the browser can steal session cookies and perform actions as the victim; federated waypoint data can propagate the impact to other Wanderer instances (S0).
What should be done?
- Upgrade to version 0.19.3 as indicated in the vendor advisory (S0)
- Sanitize waypoint.icon input on the server side
- Disable federation feature if not required
- Monitor and log suspicious waypoint submissions
- Harden authentication controls for waypoint creation
- Follow official advisories since patch status is currently unknown

Show the technical text from the sources
Wanderer is a self-hosted trail database for saving and sharing adventures. Prior to 0.19.3, an authenticated user can store a crafted waypoint.icon value that createMarkerFromWaypoint() passes into FontawesomeMarker, where insertAdjacentHTML inserts the unvalidated value into map marker markup. Opening the affected trail map executes attacker-controlled script in the viewer's browser, which can expose session tokens or perform actions as the victim. Federated waypoint data can also reach the sink without a local account on the receiving instance. This issue is fixed in version 0.19.3.
