npm install subtext@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 subtext

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-2mvq-xp48-4c77, inspect your project dependencies using npm:

npm ls subtext

Analyze the terminal output to locate any version of Subtext 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 subtext 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Subtext, 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 `subtext` are vulnerable to Denial of Service (DoS). The package fails to enforce the `maxBytes` configuration for payloads with chunked encoding that are written to the file system. This allows attackers to send requests with arbitrary payload sizes, which may exhaust system resources leading to Denial of Service. ## Recommendation This package is not actively maintained and has been moved to `@hapi/subtext` where version 6.1.2.
