# CVE-2026-62344: Wanderer: Unauthenticated Access to Private Trails and Comments via ActivityPub Endpoints

Status: published. Published: 2026-11-06. Updated: 2026-11-11.

Wanderer is a self-hosted trail database for saving and sharing adventures. Prior to 0.19.3, the unauthenticated GET /activitypub/trail/{id} and GET /activitypub/comment/{id} endpoints call ActivitypubTrail() and ActivitypubComment() to return full trail and comment records without applying the PocketBase collection view rules. An attacker who can enumerate or guess record IDs can retrieve private trail names, descriptions, GPS coordinates, GPX file URLs, photo URLs, and comments. This issue is fixed in version 0.19.3.
