CVE-2021-21291 Open this link in a new tabHow to fix?
Upgrade github.com/oauth2-proxy/oauth2-proxy
to version 7.0.0 or higher.
Overview
github.com/oauth2-proxy/oauth2-proxy is a reverse proxy that provides authentication with Google, Github or other providers.
Affected versions of this package are vulnerable to Open Redirect. For users that use the whitelist domain feature, a domain that ended in a similar way to the intended domain could have been allowed as a redirect.
For example, if a whitelist domain was configured for .example.com
, the intention is that subdomains of example.com
are allowed. Instead, example.com
and badexample.com
could also match.
