Name of the Vulnerable Software and Affected Versions Drupal OpenID Connect / OAuth client versions prior to 1.5.0

Description A flaw exists in the OpenID Connect / OAuth client module that allows for privilege escalation due to improper handling of case sensitivity. The module does not adequately validate the uniqueness of user fields, potentially allowing a user to register with an email address already associated with another account. This can lead to data integrity issues when a user signs in for the first time.

Recommendations Update to version 1.5.0 or later.
