No CVSS score has been assigned to CVE-2025-59844 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-59844?

CVE-2025-59844 affects the following packages: SonarSource/sonarqube-scan-action (GitHub Actions). Ecosystems affected: GitHub Actions.

How do I fix CVE-2025-59844?

Update SonarSource/sonarqube-scan-action to 6.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-59844 is resolved across your whole dependency graph.

How do I detect CVE-2025-59844 in my GitHub Actions dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for SonarSource/sonarqube-scan-action, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-59844 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2025-59844 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-59844 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-59844?

CVE-2025-59844 has an EPSS (Exploit Prediction Scoring System) score of 1.5%, placing it in the 74th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-59844?

CVE-2025-59844 is classified as OS Command Injection (CWE-78). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-59844 published, and has it been updated?

CVE-2025-59844 was published on September 26, 2025 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

SonarQube Server and Cloud is a static analysis solution for continuous code quality and security inspection. A command injection vulnerability exists in SonarQube GitHub Action in version 4.0.0 to before version 6.0.0 when workflows pass user-controlled input to the args parameter on Windows runners without proper validation. This vulnerability bypasses a previous security fix and allows arbitrary command execution, potentially leading to exposure of sensitive environment variables and compromise of the runner environment. The vulnerability has been fixed in version 6.0.0. Users should upgrade to this version or later.
