High CVSS 8
CVE-2026-50365
Improper authentication in Windows RPC API allows an unauthorized attacker to elevate privileges over an adjacent network.
What this means
- Exposure
- Exploitable from the adjacent network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- The authentication mechanism can be bypassed, letting an attacker pose as a legitimate user.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
