DescriptionNVD

A vulnerability in SQL Expressions allows an authenticated attacker to read arbitrary files from the Grafana server's filesystem. Only instances with the sqlExpressions feature toggle enabled are vulnerable.

AnalysisAI

Arbitrary file read in Grafana OSS exposes server filesystem contents to authenticated low-privilege users when the sqlExpressions feature toggle is enabled. Affected versions span the 11.6.x, 12.x, and 13.0.x release trains, with fixed security builds available across all affected branches. …

Vulnerability AssessmentAI

Exploitation Exploitation requires two concurrent conditions: first, the sqlExpressions feature toggle must be explicitly enabled in the Grafana instance configuration - this is a non-default setting that must be deliberately activated by an administrator; second, the attacker must hold a valid authenticated Grafana account with at least low-privilege access (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.3 score reflects meaningful but bounded risk: the network attack vector (AV:N) confirms remote reachability, but high attack complexity (AC:H) and low privilege requirement (PR:L) together indicate exploitation is not trivial and requires an authenticated session plus non-default configuration. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with a valid low-privilege Grafana account on an instance where the sqlExpressions feature toggle has been enabled crafts a malicious SQL expression referencing a sensitive filesystem path (such as /etc/passwd or application secret files) and submits it through the Grafana query interface or API. The server evaluates the expression and returns the file contents in the query response, allowing the attacker to systematically enumerate and exfiltrate sensitive server-side files. …
Remediation The primary remediation is to upgrade Grafana OSS to the appropriate security-patched release for your branch: 11.6.14+security-04, 12.2.8+security-04, 12.3.6+security-04, 12.4.3+security-02, or 13.0.1+security-01, as detailed in the Grafana security advisory at https://grafana.com/security/security-advisories/cve-2026-33380. … Detailed patch versions, workarounds, and compensating controls in full report.
