How to Fix CVE-2022-24794

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

express-openid-connect fixed: 2.7.2 
npm install express-openid-connect@2.7.2
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 express-openid-connect

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-24794, inspect your project dependencies using npm:

npm ls express-openid-connect

Analyze the terminal output to locate any version of Express openid connect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.2), your application is affected.

Note: The npm ls express-openid-connect 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-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Express openid connect, 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

### Impact 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 sanitised. ### Am I affected? You are affected by this vulnerability if you are using the `requiresAuth` middleware on a catch all route or the default `authRequired` option and `express-openid-connect` version `<=2.7.1`. ### How to fix that? Upgrade to version `>=2.7.2` ### Will this update impact my users? The fix provided in the patch will not affect your users.
