CVE-2022-24794

URL Redirection to Untrusted Site ('Open Redirect') in express-openid-connect

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.

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.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

CVE-2022-24794 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.7.2); upgrading removes the vulnerable code path.

1. What is CVE-2022-24794? CVE-2022-24794 is a high-severity open redirect vulnerability in express-openid-connect (npm), affecting versions < 2.7.2. It is fixed in 2.7.2. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is CVE-2022-24794? CVE-2022-24794 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of express-openid-connect are affected by CVE-2022-24794? express-openid-connect (npm) versions < 2.7.2 is affected.
4. Is there a fix for CVE-2022-24794? Yes. CVE-2022-24794 is fixed in 2.7.2. Upgrade to this version or later.
5. Is CVE-2022-24794 exploitable, and should I be worried? Whether CVE-2022-24794 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2022-24794 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2022-24794? Upgrade express-openid-connect to 2.7.2 or later.
