CVE-2026-1814

Credential disclosure via low-entropy keystore passwords

Published Feb 3, 2026 · Updated Feb 3, 2026

Insufficient entropy in Rapid7 InsightVM/Nexpose 6.4.50 through 8.35.0 allows local users to decrypt stored scanner credentials. CredentialsKeyStorePassword.generateRandomPassword() prepends a static p to only 6–11 random characters when replacing the legacy nsc.ks password. Exploitation requires high-privileged access to the nsc.ks file and offline brute force; it exposes credentials stored for Security Console scanning but does not alter them or interrupt service.
