How to Fix CVE-2023-26110

To remediate this vulnerability, upgrade all affected Node bluetooth 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-bluetooth fixed: Latest secure release 
npm install node-bluetooth@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 node-bluetooth

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-26110, inspect your project dependencies using npm:

npm ls node-bluetooth

Analyze the terminal output to locate any version of Node bluetooth 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 node-bluetooth 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 bluetooth, 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 the package node-bluetooth are vulnerable to Buffer Overflow via the findSerialPortChannel method due to improper user input length validation.
