CVE-2026-100836 Edgeless Systems Contrast through 1.20.0 Denial of Service via ciphertextContainer

Contrast through 1.20.0 contains a panic vulnerability in the transit-engine endpoint's ciphertextContainer.UnmarshalJSON function that fails to validate decoded ciphertext length before slicing. An authenticated workload with a valid mesh certificate can trigger a runtime panic by submitting a...

CVE-2026-100836

Contrast through 1.20.0 is vulnerable to a Denial of Service (DoS) via a panic in the transit-engine endpoint's ciphertextContainer.UnmarshalJSON function. The root cause is a failure to validate decoded ciphertext length before slicing. An authenticated workload with a valid mesh certificate can...

CVE-2026-100839

In versions before 1.18.0 , the Contrast confidential-computing runtime for Kubernetes is vulnerable to an AML injection attack (known as "BadAML"). An attacker controlling the host can pass malicious, Turing-complete AML bytecode via ACPI tables to the guest firmware (OVMF) and the Linux kernel....

CVE-2026-100839 Contrast before 1.18.0 AML Injection Remote Code Execution

Contrast is a confidential-computing runtime for Kubernetes. In versions before 1.18.0, the guest kernel's ACPI/AML handling is vulnerable to an AML injection attack "BadAML". ACPI tables containing AML bytecode are passed from the untrusted host QEMU to the guest firmware OVMF and on to the Linu...

EUVD-2026-87850

Contrast is a confidential-computing runtime for Kubernetes. In versions before 1.19.1, the Kata agent policies generated by the Contrast CLI contained a flaw in the CopyFile verification that allowed arbitrary writes to the guest root filesystem. A malicious process on the untrusted host able to...

CVE-2026-100838

The Contrast confidential-computing runtime for Kubernetes (versions before 1.19.1 ) contains a flaw in the CopyFile verification of policies generated by the Contrast CLI. This vulnerability allows a malicious process on an untrusted host, capable of connecting to the Kata agent VSOCK , to issue...

CVE-2026-100835 Contrast before 1.16.0 Remote Attestation Relay Attack

Contrast before 1.16.0 is susceptible to remote attestation relay attacks. Contrast accepted any TEE attestation report that verified correctly and contained the expected firmware patch levels and software measurements, regardless of which machine produced it, so attestation was not bound to...

CVE-2026-100835

Contrast versions prior to 1.16.0 are vulnerable to a remote attestation relay attack . The root cause is that the software accepts any valid TEE attestation report containing the correct firmware patch levels and software measurements without binding the attestation to specific, physically trust...
