SCA: security update for github.com/oauth2-proxy/oauth2-proxy (GHSA-j7px-6hwj-hpjg)

medium Tenable Self-Hosted Container Security Plugin ID 433489

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In OAuth2 Proxy before 5.1.1, there is an open redirect vulnerability. Users can provide a redirect
 address for the proxy to send the authenticated user to at the end of the authentication flow. This is
 expected to be the original URL that the user was trying to access. This redirect URL is checked within
 the proxy and validated before redirecting the user to prevent malicious actors providing redirects to
 potentially harmful sites. However, by crafting a redirect URL with HTML encoded whitespace characters the
 validation could be bypassed and allow a redirect to any URL provided. This has been patched in 5.1.1.
 (CVE-2020-11053)
