Summary
Kroxylicious-kms-provider-azure-key-vault-kms: streams for apache kafka kroxylicious: azure key vault ssrf exfiltrates bearer token via untrusted edek vaultname
Details

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.
