Summary
Kroxylicious, a proxy for Apache Kafka, is affected through its ACL authorizer, which uses prefix matching to apply access rules. An authenticated Kafka client may be able to access resources, such as reading a topic, that the ACL configuration should deny.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
A flaw was found in the Kroxylicious ACL authorizer. Its prefix-matching logic may apply a rule to a principal of a different type, or fail to check a broader matching rule when prefixes overlap. Depending on the ACL configuration, this may allow an authenticated Kafka client to access a resource (such as read a topic) that should be denied.
