How to Fix CVE-2019-10805

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

valib fixed: Latest secure release 
npm install valib@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 valib

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-10805, inspect your project dependencies using npm:

npm ls valib

Analyze the terminal output to locate any version of Valib 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 valib 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Valib, 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

valib through 2.0.0 allows Internal Property Tampering. A maliciously crafted JavaScript object can bypass several inspection functions provided by valib. Valib uses a built-in function (hasOwnProperty) from the unsafe user-input to examine an object. It is possible for a crafted payload to overwrite this function to manipulate the inspection results to bypass security checks.
