This discrepancy can result in misconfigured Access Control Lists (ACLs) and unintended security postures, like granting READ permission to users who should not be able to join/sync groups, or allowing users without READ permission (but with DESCRIBE permission) to access sensitive group metadata.\n\nThe correct permission for CONSUMER_GROUP_DESCRIBE API is DESCRIBE GROUP so the current implementation is correct. However, the kafka documentation as well as the KIP-848 will be updated to reflect the correct permission. We advise the Kafka users to review existing group ACLs to ensure the principle of least privilege."}], "lastModified": "2026-06-03T02:04:19.880", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:kafka:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "61D7227C-2896-457A-AE72-7D2957DACF19", "versionEndIncluding": "4.3.0", "versionStartIncluding": "4.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
