Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade TÜBİTAK BİLGEM Software Technologies Research Institute eta-remote to 0.0.3 or later.
- Segment the networks that can reach it.

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
- Local network segment. The attacker must share a network segment with the target.
- 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 TÜBİTAK BİLGEM Software Technologies Research Institute eta-remote run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
