# CVE-2026-62764

> 5.7 MEDIUM · 🧪 PoC

## Beschreibung

Improper Handling of Insufficient Privileges vulnerability in Apache Accumulo.
An authenticated, but low-privileged user without system permissions may
issue a remote command to gracefully shutdown system components
(compaction-coordinator, compactor, gc, manager, monitor, tserver, or sserver),
leading to a denial of service.

This issue affects Apache Accumulo 2.1.4 and 2.1.5.

Users are recommended to upgrade to version 2.1.6, which fixes the issue.
