How to Fix GHSA-7x92-2j68-h32c

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

featurebook fixed: Latest secure release 
npm install featurebook@Latest secure release
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 featurebook

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-7x92-2j68-h32c, inspect your project dependencies using npm:

npm ls featurebook

Analyze the terminal output to locate any version of Featurebook in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls featurebook 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Featurebook, 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

Affected versions of `featurebook` resolve relative file paths, resulting in a directory traversal vulnerability. A malicious actor can use this vulnerability to access files outside of the intended directory root, which may result in the disclosure of private files on the vulnerable system. The `featurebook` package is not intended to be run in production code nor to be exposed to an untrusted network. ## Proof of Concept ``` GET /../../../../../../../../../../etc/passwd HTTP/1.1 host:foo ``` ## Recommendation No direct patch is currently available. At this time, the best mitigation is to ensure that `featurebook` is not running in production or exposed to an untrusted network.
