CVE-2026-91881Network attack vectorHinoki check available

Credential interception via disabled TLS certificate verification

Published Oct 14, 2026 · Updated Oct 14, 2026

Dell Terraform Provider for Redfish before 1.6.2 allows man-in-the-middle attackers to read credentials via its HTTP transport. The base transport unconditionally disables TLS certificate verification, accepting untrusted server certificates for Redfish BMC connections. Exploitation requires interception of provider-to-BMC traffic, requires no attacker authentication, and exposes management traffic and credentials usable for unauthorized access.
