What it is
Changing an identifier in a request reaches another user's records.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything.
What an attacker gains

Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade open-wanderer wanderer to 0.19.3 or later.
- Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
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.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
- Multi-tenant services. The flaw sits between one role or tenant and another.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
Questions to answer about your own systems
- Where does open-wanderer wanderer run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
