CVE-2021-34538: Apache Hive

High severity, CVSS 7.5. EPSS: 1.9% chance of exploitation in the next 30 days.

Apache Hive before 3.1.3 "CREATE" and "DROP" function operations does not check for necessary authorization of involved entities in the query. It was found that an unauthorized user can manipulate an existing UDF without having the privileges to do so. This allowed unauthorized or underprivileged users to drop and recreate UDFs pointing them to new jars that could be potentially malicious.

Affected products

• Apache Hive: before 3.1.3 (fixed in 3.1.3)
