Summary

Red Hat streams for Apache Kafka 3 ships the Kroxylicious Azure Key Vault KMS provider, which accepts an untrusted vaultName from wire-deserialized EDEK bytes without format validation. This flaw, CWE-918, enables server-side request forgery that sends the proxy's Azure bearer token to an attacker-controlled host. An attacker with low privileges can reach this over the network without user interaction, and replaying the stolen token against the real Key Vault defeats the record-encryption trust model.

Description from the CNA

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.
