Critical CVSS 10
CVE-2026-69555
Incorrect authorization in Azure Arc allows an unauthorized attacker to elevate privileges over a network.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data and modify or destroy data. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- An authorisation check exists but its logic is wrong.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
