Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | express-openid-connect | < 2.7.2 | 2.7.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
