How to Fix CVE-2025-59844

To remediate this vulnerability, upgrade all affected SonarSource/sonarqube scan action dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

SonarSource/sonarqube-scan-action fixed: 6.0.0 
Upgrade SonarSource/sonarqube-scan-action to 6.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for SonarSource/sonarqube-scan-action

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-59844, inspect your project dependencies for SonarSource/sonarqube scan action:

inspect dependencies for SonarSource/sonarqube-scan-action

Analyze the terminal output to locate any version of SonarSource/sonarqube scan action in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.0.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In SonarSource/sonarqube scan action, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A command injection vulnerability exists in SonarQube GitHub Action prior to v6.0.0 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. ### Patches The vulnerability has been fixed in version v6.0.0. Users should upgrade to this version or later. ### Credits Francois Lajeunesse-Robert (Boostsecurity.io) ### References - Community Post: https://community.sonarsource.com/t/sonarqube-scanner-github-action-v6/149281 - Fix release: https://github.com/SonarSource/sonarqube-scan-action/releases/tag/v6.0.0
