How to Fix GHSA-cfqx-f43m-vfh7
To remediate this vulnerability, upgrade all affected @saltcorn/server 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 @saltcorn/server@1.0.0-beta.14Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @saltcorn/serverHow to Check if You Are Affected
To determine whether your Node.js application is affected by GHSA-cfqx-f43m-vfh7, inspect your project dependencies using npm:
npm ls @saltcorn/serverAnalyze the terminal output to locate any version of @saltcorn/server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0-beta.14), your application is affected.
Note: The npm ls @saltcorn/server command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
