CVE-2026-18129Network attack vector

Credential disclosure via unvalidated external SQL certificates

Published Aug 11, 2026 · Updated Aug 11, 2026

Cleartext transmission in Ivanti Endpoint Manager before 2024 SU7 allows remote attackers to obtain external SQL credentials through MITM interception. The Core fails to validate the external SQL server certificate, allowing an impersonated database endpoint to receive connection credentials. Exploitation requires remote attackers able to intercept or redirect Core-to-database traffic; the exposed credentials can compromise the configured external SQL connection.
