27 Mar 2026 — A chained attack via SQL Expressions and a Grafana Enterprise plugin can lead to a remote arbitrary code execution impact (RCE). This is enabled by a feature in Grafana (OSS), so all users are always recommended to update to avoid future attack vectors going this path. Only instances with the sqlExpressions feature toggle enabled are vulnerable. Only instances in the following version ranges are affected: - 11.6.0 (inclusive) to 11.6.14 (exclusive): 11.6.14 has the fix. 11.5 and below are not affected. - 12... • https://grafana.com/security/security-advisories/cve-2026-27876 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

https://notcve.org/view.php?id=CVE-2022-39324
27 Jan 2023 — Grafana is an open-source platform for monitoring and observability. Prior to versions 8.5.16 and 9.2.8, malicious user can create a snapshot and arbitrarily choose the `originalUrl` parameter by editing the query, thanks to a web proxy. When another user opens the URL of the snapshot, they will be presented with the regular web interface delivered by the trusted Grafana server. The `Open original dashboard` button no longer points to the to the real original dashboard but to the attacker’s injected URL.

CVSS: 6.7EPSS: 0%CPEs: 2EXPL: 0CVE-2022-39307 – Grafana subject to Exposure of Sensitive Information resulting in User enumeration via forget password
https://notcve.org/view.php?id=CVE-2022-39307
09 Nov 2022 — Grafana is an open-source platform for monitoring and observability. When using the forget password on the login page, a POST request is made to the `/api/user/password/sent-reset-email` URL. When the username or email does not exist, a JSON response contains a “user not found” message. This leaks information to unauthenticated users and introduces a security risk. This issue has been patched in 9.2.4 and backported to 8.5.15. • https://github.com/grafana/grafana/security/advisories/GHSA-3p62-42x7-gxg5 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-209: Generation of Error Message Containing Sensitive Information •
