Vulnerability from github – Published: 2026-07-17 09:31 – Updated: 2026-07-17 09:31

Details

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.

Severity

5.7 (Medium)
