This only impacts apps that have the embeddedAsarIntegrityValidation and onlyLoadAppFromAsar fuses enabled. Apps without these fuses enabled are not impacted. This issue is specific to macOS as these fuses are only currently supported on macOS.

Specifically this issue can only be exploited if your app is launched from a filesystem the attacker has write access too. i.e. the ability to edit files inside the resources folder in your app installation on Windows which these fuses are supposed to protect against.

CVE-2023-44402 has a CVSS score of 6.1 (Medium). The vector is requires local access, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (22.3.24, 24.8.3, 25.8.1, 26.2.1, 27.0.0-alpha.7); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2023-44402? CVE-2023-44402 is a medium-severity security vulnerability in electron (npm), affecting versions < 22.3.24. It is fixed in 22.3.24, 24.8.3, 25.8.1, 26.2.1, 27.0.0-alpha.7.
2. How severe is CVE-2023-44402? CVE-2023-44402 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of electron are affected by CVE-2023-44402? electron (npm) versions < 22.3.24 is affected.
4. Is there a fix for CVE-2023-44402? Yes. CVE-2023-44402 is fixed in 22.3.24, 24.8.3, 25.8.1, 26.2.1, 27.0.0-alpha.7. Upgrade to this version or later.
5. Is CVE-2023-44402 exploitable, and should I be worried? Whether CVE-2023-44402 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-44402 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
