Alpine Linux: grafana fixed in 12.4.4-r0
AnalysisAI
Denial of service in Grafana OSS (multiple 11.6.x, 12.2.x, 12.3.x, 12.4.x and 13.0.x branches) lets remote attackers exhaust server resources and crash or hang the analytics dashboard, per an Alpine Linux advisory that ships the fix in package build 12.4.4-r0. The flaw is an uncontrolled-resource-consumption (CWE-400) condition scored CVSS 7.5 with availability-only impact; no confidentiality or integrity loss occurs. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker requires network reachability to the Grafana HTTP service, and per the supplied CVSS vector no privileges (PR:N) or user interaction (UI:N) are needed against affected versions (Grafana OSS 11.6.0-11.6.14, 12.2.0-12.2.8, 12.3.0-12.3.6, 12.4.0-12.4.3, 13.0.0-13.0.1). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) describes a network-reachable, low-complexity, no-privilege, no-interaction attack yielding high availability impact - a strong theoretical DoS signal. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach the Grafana web service sends specially crafted or high-cost requests that trigger the uncontrolled resource consumption, driving CPU or memory usage until the instance becomes unresponsive and dashboards/alerting go dark. Because the CVSS vector rates attack complexity low and no user interaction, a single automated client could sustain the condition; no public exploit is currently identified. |
| Remediation | Upgrade Grafana to a fixed release beyond the affected ranges - on Alpine Linux, update the grafana package to 12.4.4-r0 or later (Vendor-released patch: 12.4.4-r0); for upstream Grafana OSS, move to the first patched build above your branch's affected upper bound (e.g. … Detailed patch versions, workarounds, and compensating controls in full report. |
