This vulnerability allows attackers who have control over a given apps update server / update storage to serve maliciously crafted update packages that pass the code signing validation check but contain malicious code in some components.

Please note that this kind of attack would require significant privileges in your own auto updating infrastructure and the ease of that attack entirely depends on your infrastructure security.

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

CVE-2022-29257 has a CVSS score of 6.6 (Medium). The vector is network-reachable, high privileges required, and no user interaction. 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 (15.5.0, 16.2.0, 17.2.0, 18.0.0-beta.6); upgrading removes the vulnerable code path.

1. What is CVE-2022-29257? CVE-2022-29257 is a medium-severity improper input validation vulnerability in electron (npm), affecting versions < 15.5.0. It is fixed in 15.5.0, 16.2.0, 17.2.0, 18.0.0-beta.6. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
2. How severe is CVE-2022-29257? CVE-2022-29257 has a CVSS score of 6.6 (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-2022-29257? electron (npm) versions < 15.5.0 is affected.
4. Is there a fix for CVE-2022-29257? Yes. CVE-2022-29257 is fixed in 15.5.0, 16.2.0, 17.2.0, 18.0.0-beta.6. Upgrade to this version or later.
5. Is CVE-2022-29257 exploitable, and should I be worried? Whether CVE-2022-29257 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-2022-29257 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.
7. How do I fix CVE-2022-29257?
   • Upgrade electron to 15.5.0 or later
   • Upgrade electron to 16.2.0 or later
   • Upgrade electron to 17.2.0 or later
   • Upgrade electron to 18.0.0-beta.6 or later
