CVE-2026-91881
CriticalCVSS 9.0Summary
Dell Terraform Provider for Redfish before version 1.6.2 contains an Improper Certificate Validation vulnerability in the HTTP transport component, allowing an unauthenticated attacker to intercept all Redfish BMC traffic including credentials via man-in-the-middle attack.
Risk Assessment
An attacker can gain unauthorized access to data and systems managed by Redfish, leading to severe security compromise.
Recommendation
Upgrade Dell Terraform Provider for Redfish to version 1.6.2 or later and ensure TLS certificate verification is enabled.

KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential; the JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, allowing the attacker to obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations.

A vulnerability in the Advanced Malware Protection (AMP) feature of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to write arbitrary files on the underlying operating system. It is due to improper handling of email attachments when the file reputation service is enabled; an attacker could send an email with a crafted attachment through an affected device, potentially allowing arbitrary file writes and command execution with root privileges.

A missing authentication vulnerability in Lantronix XPress-DR and XPress-DR-I (CoBos-family) firmware through 8.1.0.0 allows remote attackers to read and persistently overwrite device configuration by sending crafted frames to the unauthenticated UDP configuration protocol on port 30718. Attackers can send a type 0xF8 query to read live configuration data and a type 0xFD frame with exactly 0x78 body bytes to rewrite the device IP address and serial-channel forwarding records, causing changes to commit to EEPROM and persist across reboots. The XPress-DR product series reached end-of-life/end-of-support in February 2025.

Original NVD description (English source)
Dell Terraform Provider for Redfish, versions prior to 1.6.2, contains an Improper Certificate Validation vulnerability in the HTTP transport component. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information exposure and unauthorized access. This is a Critical severity vulnerability as it allows an unauthenticated attacker to intercept all Redfish BMC traffic including credentials by performing a man-in-the-middle attack, since TLS certificate verification is unconditionally disabled in the base HTTP transport. Dell recommends customers to upgrade at the earliest opportunity.
