NewCVE-2025-27817 (opens in a new tab)How to fix?
Upgrade org.apache.kafka:kafka-clients to version 3.9.1 or higher.
Overview
org.apache.kafka:kafka-clients is a streaming platform that can publish and subscribe to streams of records, store streams of records in a fault-tolerant durable way, and process streams of records as they occur.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) due to the improper handling of sasl.oauthbearer.token.endpoint.url and sasl.oauthbearer.jwks.endpoint.url configurations. An attacker can read arbitrary contents of the disk and environment variables or make requests to an unintended location by manipulating these configurations.
Note: This is only exploitable if configurations can be specified by an untrusted party.
