{"id":"CVE-2026-62345","published":"2026-11-06T19:17:53.607","lastModified":"2026-11-09T23:17:24.200","description":"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.","cvssScore":7.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/open-wanderer/wanderer/commit/6135332ea69a3d9a4fe1dec5af1cb1ee74f70e2b","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/pull/1093","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/releases/tag/v0.19.3","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/security/advisories/GHSA-hx3v-rv4v-w875","tags":[]}],"exploitRefs":[{"url":"https://github.com/open-wanderer/wanderer/commit/6135332ea69a3d9a4fe1dec5af1cb1ee74f70e2b","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/pull/1093","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/releases/tag/v0.19.3","tags":[]},{"url":"https://github.com/open-wanderer/wanderer/security/advisories/GHSA-hx3v-rv4v-w875","tags":[]}],"hasPoc":true,"ai":null}
