Exploitation Conditions

Exploitation conditions cannot be determined - no vulnerability description, CVSS vector, or CWE is available. The required authentication level, attack vector (network vs. local), configuration prerequisites, and affected Grafana features are all unknown. Security teams cannot assess whether default Grafana deployments are at risk or whether a specific plugin, data source, or configuration is required. Verification against a Grafana Labs advisory is mandatory before any exploitation condition can be stated.

Impact

Risk cannot be meaningfully assessed from available data. No CVSS vector is present, so attack vector, complexity, privilege requirements, and impact scope are all unknown. No EPSS score is available, KEV status is negative (not listed in CISA KEV), and no POC has been identified. The sole data point is an Alpine Linux package bump, which could correspond to anything from a critical unauthenticated RCE to a low-severity information disclosure. CVSS indicates N/A and CWE is absent - these are not conflicting signals, they are missing signals. Security teams should treat this as unclassified until Grafana Labs publishes a corresponding security advisory or CVE enrichment becomes available from NVD.

Exploit ScenarioDerived

An attack scenario cannot be constructed from available data. The vulnerability description contains no information about how an attacker would interact with a vulnerable Grafana instance, what component is targeted, or what outcome is achievable. No POC exists in the provided intelligence, and no exploit technique can be inferred without a CWE or CVSS vector.

AnalysisAIv1 – Jun 13, 2026

Grafana received a security fix in Alpine Linux's package repository, published as version 12.4.4-r0. The underlying vulnerability details, attack vector, and impact class are not disclosed in available intelligence data. No CVSS score, CWE classification, or vendor advisory from Grafana Labs has been identified at time of analysis, making independent risk assessment impossible beyond confirming that Alpine Linux maintainers deemed the fix security-relevant.

RemediationAI

Alpine Linux users should upgrade the Grafana package to 12.4.4-r0 or later using 'apk upgrade grafana'. This is the only confirmed remediation step available from current data. No workarounds or compensating controls can be recommended because the vulnerability type and affected component are unknown - disabling specific features or restricting network access requires knowing what the flaw is. Users on other distributions should consult Grafana Labs' security page directly. No patch version from Grafana Labs upstream has been independently confirmed; the fix version is inferred from the Alpine package revision only.

Technical ContextAI · show details

Grafana is a widely deployed open-source data visualization and analytics platform. Alpine Linux distributes Grafana as an apk package; the version string 12.4.4-r0 follows Alpine's packaging convention where '12.4.4' represents the upstream Grafana release version and '-r0' denotes the Alpine package revision. No CWE root cause class is available in the provided data, and no CPE string was supplied to narrow the affected component within the Grafana stack (frontend, backend API, plugin subsystem, etc.). The specific Grafana upstream release that introduced the fix is inferred to be 12.4.4, but this has not been independently confirmed against Grafana Labs' own changelog or security advisories.
