CVE-2026-118952

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.
