How to Fix GHSA-jcgr-9698-82jx

To remediate this vulnerability, upgrade all affected @floffah/build dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@floffah/build fixed: 1.0.0 
npm install @floffah/build@1.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @floffah/build

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-jcgr-9698-82jx, inspect your project dependencies using npm:

npm ls @floffah/build

Analyze the terminal output to locate any version of @floffah/build 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), your application is affected.

Note: The npm ls @floffah/build command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In @floffah/build, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If you are using the esbuild target or command you are at risk of code/option injection. Attackers can use the command line option to maliciously change your settings in order to damage your project. ### Patches The problem has been patched in v1.0.0 as it uses a proper method to pass configs to esbuild/estrella. ### Workarounds There is no work around. You should update asap. ### Notes This notice is mainly just to make sure people update to the latest version. This isn't that bad, but should encourage you to update.
