What is CVE-2026-1814?
CVE-2026-1814 is a medium-severity vulnerability in Rapid7 InsightVM/Nexpose, published on 3 Feb 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Rapid7 Nexpose versions 6.4.50 and later are vulnerable to an insufficient entropy issue in the CredentialsKeyStorePassword.generateRandomPassword() method. When updating legacy keystore passwords, the application generates a new password with insufficient length (7-12 characters) and a static prefix 'p', resulting in a weak keyspace. An attacker with access to the nsc.ks file can brute-force this password using consumer-grade hardware to decrypt stored credentials.
