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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-118952","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2563276","tags":[]},{"url":"https://github.com/kroxylicious/kroxylicious/security/advisories/GHSA-qvv3-6w3q-hgqc","tags":[]}],"exploitRefs":[{"url":"https://github.com/kroxylicious/kroxylicious/security/advisories/GHSA-qvv3-6w3q-hgqc","tags":[]}],"hasPoc":true,"ai":null}
