Until an official fix is available, restrict Viewer role permissions or monitor for unusual query patterns that may trigger excessive memory allocation. Avoid running untrusted SQL Expression queries.
Description
CVE-2026-107509 is a vulnerability in Grafana OSS where a user with the Viewer role can cause the application to allocate an unbounded amount of memory by submitting a single SQL Expression query that casts a value to a very large BINARY length. This excessive memory allocation can lead to a crash of the Grafana service. The affected versions include 13.1.0 through 13.1.9, 13.2.0 through 13.2.5, and 13.3.0. The vulnerability has a medium severity rating with a CVSS score of 6.5 and does not impact confidentiality or integrity but affects availability.
