What is CVE-2026-62764?

An authentication flaw in Apache Accumulo allows low-privileged users, who lack sufficient system permissions, to remotely issue commands that can gracefully shut down essential system components such as the compaction-coordinator, compactor, garbage collector, manager, monitor, tserver, or sserver. This potentially leads to a denial of service, interrupting normal operations. Users of affected versions 2.1.4 and 2.1.5 are advised to upgrade to version 2.1.6, which addresses this concern.

Affected Version(s)

Apache Accumulo 2.1.4 <= 2.1.5
