# Wanderer: crafted waypoint icon runs script in trail map viewers

Link for people: https://infrastack.ai/live/CVE-2026-62345 (this .md is for agents)

Wanderer, a self-hosted trail database, inserts an unvalidated waypoint icon value into map marker HTML. Opening an affected trail map runs attacker-controlled script in the viewer's browser, which can expose session tokens or act as the victim.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the running Wanderer version; instances below `0.19.3` are affected.
- Federated waypoint data can reach the sink, so instances that accept federated content are also in scope.

## Fix

- Wanderer: upgrade to `0.19.3`.

- [advisory] Vendor advisory: github.com https://github.com/open-wanderer/wanderer/security/advisories/GHSA-hx3v-rv4v-w875
- [fix] Patch: github.com https://github.com/open-wanderer/wanderer/commit/6135332ea69a3d9a4fe1dec5af1cb1ee74f70e2b
- [fix] Release notes: github.com https://github.com/open-wanderer/wanderer/releases/tag/v0.19.3

## 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.
