npm ls asinc

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-87qw-7v97-w34r, inspect your project dependencies using npm:

npm ls asinc

Analyze the terminal output to locate any version of Asinc 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 asinc 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-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In Asinc, 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

All versions of `asinc` typosquatted a popular package of similar name and tracked users who had installed the incorrect package. The package uploaded information to a remote server including: name of the downloaded package, name of the intended package, the Node version and whether the process was running as sudo. There is no further compromise. ## Recommendation Remove the package from your dependencies and always ensure package names are typed correctly upon installation.
