How to Fix GHSA-v6cj-r88p-92rm

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

centra fixed: 2.4.0 
npm install centra@2.4.0
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 centra

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-v6cj-r88p-92rm, inspect your project dependencies using npm:

npm ls centra

Analyze the terminal output to locate any version of Centra in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.0), your application is affected.

Note: The npm ls centra 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In Centra, 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

## Denial of Service ### Impact Affected Centra versions will, when not in stream mode, buffer responses to requests into memory with no size limit. This issue affects anyone requesting content from untrusted sources. ### Patches Version 2.4.0 resolves the issue by limiting the size of buffered response body. ### Workarounds Attempting workarounds isn't recommended. Updating is preferred. ### For more information If you have any questions or comments about this advisory, open an issue in [ethanent/centra](https://github.com/ethanent/centra).
