Alpine Linux: grafana fixed in 12.4.4-r0
AnalysisAI
Denial of service in Grafana (fixed in Alpine Linux package grafana 12.4.4-r0) allows remote unauthenticated attackers to exhaust server resources and render the observability dashboard unavailable. The flaw is classified as uncontrolled resource consumption (CWE-400) with a network-reachable, no-privilege, no-interaction attack profile (CVSS 7.5, availability-only). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to a running Grafana instance (default HTTP service on TCP 3000) and no authentication or user interaction, consistent with AV:N/AC:L/PR:N/UI:N. … 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, score 7.5 High) indicates a straightforward network-based, unauthenticated attack requiring no user interaction, with impact confined entirely to availability - no confidentiality or integrity loss. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach a Grafana instance over the network sends crafted requests that trigger the uncontrolled resource consumption path, driving memory or CPU usage until the service becomes unresponsive and dashboards/alerting go dark. Because no authentication or user interaction is required, an internet-exposed instance can be knocked offline by a single low-privilege remote actor. … |
| Remediation | Vendor-released patch: upgrade the Alpine grafana package to 12.4.4-r0 or later (e.g., apk update && apk upgrade grafana), which is the fixed revision cited in the input. … Detailed patch versions, workarounds, and compensating controls in full report. |
