How to Fix GHSA-86mr-6m89-vgj3

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

node-weakauras-parser fixed: 1.0.5 
npm install node-weakauras-parser@1.0.5
node-weakauras-parser fixed: 2.0.2 
npm install node-weakauras-parser@2.0.2
node-weakauras-parser fixed: 3.0.1 
npm install node-weakauras-parser@3.0.1
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 node-weakauras-parser

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-86mr-6m89-vgj3, inspect your project dependencies using npm:

npm ls node-weakauras-parser

Analyze the terminal output to locate any version of Node weakauras parser in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.5), your application is affected.

Note: The npm ls node-weakauras-parser 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-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'), where the product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. In Node weakauras parser, 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 `node-weakauras-parser` are vulnerable to a Buffer Overflow. The `encode_weakaura` function fails to properly validate the input size. A buffer of 13835058055282163711 bytes causes an overflow on 64-bit systems. ## Recommendation Upgrade to versions 1.0.5, 2.0.2, 3.0.1 or later.
