Project: OpenID Connect / OAuth client [1]
Date: 2021-June-02
Security risk: *Moderately critical* 14∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Access bypass

Description: 
This module allows users to authenticate against an Oauth 2.0 / OpenID
Connect identity provider to login to your Drupal site.

The module doesn't sufficiently protect against unauthorized local access, by
way of using the 'password reset' facility, for users who are supposed to
only be able to log in through the identity provider. This creates a scenario
where after such a user is blocked from logging in through the identity
provider but not explicitly blocked in Drupal, they are still able to log in
by sending themselves a Drupal 'password reset' e-mail.

Solution: 
Install the latest version:

  * If you use the openid_connect module for Drupal 8/9, upgrade to
    openid_connect 8.x-1.1 [3]
  * If you use the openid_connect module for Drupal 7, upgrade to
    openid_connect 7.x-1.0 [4]
