What is CVE-2026-105941?

The Azure Key Vault KMS provider in Kroxylicious is vulnerable to a server-side request forgery (SSRF) attack due to improper handling of untrusted vault names. This vulnerability allows attackers to exploit the deserialization of EDEK bytes without appropriate format validation. As a result, an attacker can exfiltrate the Azure bearer token from the proxy, enabling token replay attempts on the legitimate Key Vault. Such actions compromise the record-encryption trust model, potentially leading to unauthorized access to sensitive data.
