DescriptionCVE.org

A testdata data-source can be used to trigger out-of-memory crashes in Grafana.

AnalysisAI

Grafana's testdata data-source plugin allows authenticated users to trigger out-of-memory (OOM) crashes, causing a denial of service affecting availability. The vulnerability requires low-privilege user authentication and network access to the affected Grafana instance, enabling local or remote attackers with valid credentials to exhaust server memory resources without user interaction. …

Vulnerability AssessmentAI

Risk Assessment The CVSS score of 6.5 reflects a medium-to-high severity denial of service condition with high availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Grafana user (e.g., one with a low-privilege viewer or editor role) crafts a specially designed query against the testdata data-source that causes the Grafana backend process to allocate memory without release, causing the server to run out of available RAM and crash. If multiple such queries are submitted or if the attacker has access to automated query scheduling, the denial of service impact can persist or recur, forcing administrators to manually restart services. …
Remediation Apply the security patch released by Grafana as detailed in the official security advisory at https://grafana.com/security/security-advisories/cve-2026-28375. … Detailed patch versions, workarounds, and compensating controls in full report.
