High CVSS 7.5
CVE-2026-40140
Beyondtrust Privileged Remote Access
BeyondTrust Remote Support and Privileged Remote Access contain a high-severity pre-authentication vulnerability in the network communication subsystem. Insufficient validation of client-supplied input may allow an unauthenticated remote attacker to trigger a denial-of-service condition affecting appliance availability.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can take the service offline.
- Weakness
- A request that is cheap for the attacker consumes unbounded resources on the server.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
