Overview
Affected versions of this package are vulnerable to Improper Authentication in the OAuth2 autolinking process. An attacker can gain unauthorized access to a victim's account by pre-registering an unverified user with the victim's email address using one OAuth2 provider, and then waiting for the victim to register with a different provider, resulting in the attacker's OAuth2 link persisting after the account is upgraded to verified.
