{"id":"BIT-grafana-2026-19475","summary":"SQL Data Source Plugin: OOM DoS via $__timeGroup macro","details":"An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected.","aliases":["CVE-2026-19475"],"modified":"2026-09-08T08:47:51.379402260Z","published":"2026-09-08T08:14:55.194Z","database_specific":{"cpes":["cpe:2.3:a:grafana:grafana:*:*:*:*:*:*:*:*","cpe:2.3:a:grafana:grafana:*:*:*:*:enterprise:*:*:*","cpe:2.3:a:grafana:grafana:*:*:*:*:-:*:*:*","cpe:2.3:a:grafana:grafana:*:*:*:*:*:go:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://grafana.com/security/security-advisories/cve-2026-19475"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-19475"}],"affected":[{"package":{"name":"grafana","ecosystem":"Bitnami","purl":"pkg:bitnami/grafana"},"ranges":[{"type":"SEMVER","events":[{"introduced":"11.6.0"},{"fixed":"12.4.10"},{"introduced":"13.0.0"},{"fixed":"13.0.8"},{"introduced":"13.1.0"},{"fixed":"13.1.5"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/grafana/BIT-grafana-2026-19475.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
