Published 2026-08-17 · Source 74b3a70d-cca6-4d34-9789-e83b222ae3be

Description

FakeFish handles incoming credentials by passing them down to scripts. This works for real hardware because in the end it's up to the BMC to validate them. However, KubeVirt relies on a KUBECONFIG file mounted to the container and completely ignores the credentials. This allows any user of the cluster to control VMs of the user that created fakefish, power them on and off, and mount arbitrary CD images to them.

CVE-2026-74900
openssl_encrypt versions before 1.4.0 contain a critical vulnerability in pqc.py where KEM decapsulation failures silently fall back to simulation mode, generating a deterministic shared secret from only 16 bytes of the private key and publicly available encapsulated key data. Attackers who obtain 16 bytes of the private key can compute the shared secret and decrypt all ciphertext, as the fallback triggers on any KEM failure without raising an error.
