CVE-2026-62344 · Severity: high · CVSS 7.5 · Published 2026-11-06

Wanderer is a self-hosted database for storing and sharing hiking trails and outdoor adventures. The application contains an authentication bypass vulnerability in its ActivityPub endpoints that allows unauthenticated attackers to retrieve private trail information including GPS coordinates, photos, descriptions, and comments by guessing or enumerating record IDs. This exposes sensitive location data and personal information that should be restricted to authorized users.

## How to fix

## Technical details

The GET /activitypub/trail/{id} and GET /activitypub/comment/{id} endpoints fail to apply PocketBase collection view access controls before returning record data. An unauthenticated attacker can enumerate or predict numeric record IDs to retrieve private trails and comments without authorization. The vulnerability is an Insecure Direct Object Reference (IDOR) affecting the ActivitypubTrail() and ActivitypubComment() functions, which are now patched to enforce access control checks via CanAccessRecord().
