Executive Summary

This vulnerability occurs in the Auth0 Next.js SDK versions 4.11.0 through 4.11.2 and 4.12.0, where simultaneous requests on the same client may cause improper lookups in the TokenRequestCache for the request results. This means that when multiple requests happen at the same time, the SDK might return incorrect token data due to cache mishandling.

Impact Analysis

The impact of this vulnerability is that it can lead to incorrect token data being returned during simultaneous requests, potentially causing authentication errors or unauthorized access scenarios. According to the CVSS score, it has a high impact on confidentiality and a low impact on integrity, with no impact on availability.

Mitigation Strategies

Upgrade the Auth0 Next.js SDK to version 4.11.2 or later, or 4.12.1 or later, as these versions contain the fix for the improper TokenRequestCache lookups issue.
