Vulnerability from cvelistv5 – Published: 2026-09-08 20:18 – Updated: 2026-09-10 14:44

Title

Improper Cache Isolation in auth0/react-native-auth0 SDK Web Platform Credential Management

Summary

The react-native-auth0 SDK's web platform implementation does not scope its in-memory token cache to individual user sessions when operating in a server-side rendering (SSR) environment where module state persists across HTTP requests. Under the listed preconditions, tokens cached in module memory can be retrieved across subsequent requests processed by the same server runtime.

Severity

6.5 (Medium)
