CVE-2026-105941

The Azure Key Vault KMS provider in Kroxylicious accepts an untrusted vaultName from wire-deserialized EDEK bytes without format validation, enabling SSRF that exfiltrates the proxy's Azure bearer token to an attacker-controlled host. Token replay against the real Key Vault defeats the entire record-encryption trust model.
