Security Impact
CVSS: 7.5
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
How to Fix CVE-2023-22467
To remediate this vulnerability, upgrade all affected Luxon dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install luxon@1.28.1npm install luxon@2.5.2npm install luxon@3.2.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls luxonHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2023-22467, inspect your project dependencies using npm:
npm ls luxonAnalyze the terminal output to locate any version of Luxon in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.28.1), your application is affected.
Note: The npm ls luxon command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
