Technical details

This vulnerability is a chained attack involving SQL Expressions (CWE-89) and a Grafana Enterprise plugin, resulting in remote code execution (CWE-94). The vulnerability is only exploitable if the 'sqlExpressions' feature toggle is enabled. An attacker with high privileges (PR:H) can leverage this chain to execute arbitrary commands on the host system with the permissions of the Grafana process. The issue affects multiple versions across the 11.x and 12.x branches, but has been patched in versions 11.6.14, 12.1.10, 12.2.8, 12.3.6, and 12.4.2. Version 13.0.0 and later are not affected.
