How to Fix GHSA-q3w9-g74q-vp5f
To remediate this vulnerability, upgrade all affected Express fileupload 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 express-fileupload@1.1.6-alpha.6npm install express-fileupload@1.1.6-alpha.6npm install express-fileupload@1.1.6-alpha.6npm install express-fileupload@1.1.6-alpha.6npm install express-fileupload@1.1.6-alpha.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls express-fileuploadHow to Check if You Are Affected
To determine whether your Node.js application is affected by GHSA-q3w9-g74q-vp5f, inspect your project dependencies using npm:
npm ls express-fileuploadAnalyze the terminal output to locate any version of Express fileupload in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.6-alpha.6), your application is affected.
Note: The npm ls express-fileupload command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
