How to Fix CVE-2024-28849
To remediate this vulnerability, upgrade all affected Follow redirects 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 follow-redirects@1.15.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls follow-redirectsHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-28849, inspect your project dependencies using npm:
npm ls follow-redirectsAnalyze the terminal output to locate any version of Follow redirects in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.15.6), your application is affected.
