How to Fix GHSA-rmmc-8cqj-hfp3

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

otpauth fixed: 3.2.8 
npm install otpauth@3.2.8
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 otpauth

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-rmmc-8cqj-hfp3, inspect your project dependencies using npm:

npm ls otpauth

Analyze the terminal output to locate any version of Otpauth in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.8), your application is affected.

Note: The npm ls otpauth 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Otpauth, 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

Versions of `otpauth` prior to 3.2.8 are vulnerable to Authentication Bypass. The package's `totp.validate()` function may return positive values for single digit tokens even if they are invalid. This may allow attackers to bypass the OTP authentication by providing single digit tokens. ## Recommendation Upgrade to version 3.2.8 or later.
