CVE-2026-62764 Details
Description
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.
A denial-of-service vulnerability has been identified in Apache Accumulo versions 2.1.4 and 2.1.5. This issue arises from improper handling of insufficient privileges, allowing authenticated users with low privileges to issue remote commands that gracefully shut down critical system components. Affected components include the compaction coordinator, compactor, garbage collector, manager, monitor, tablet server, and server. The shutdown commands, although logged as denied, are executed by the server, disrupting service availability.
Users are advised to upgrade to Apache Accumulo version 2.1.6, which addresses this vulnerability.
