## What is CVE-2022-24794?

CVE-2022-24794 is a high-severity vulnerability in auth0 express-openid-connect, published on 31 Mar 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-601 (URL Redirection to Untrusted Site)

1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
