The LoginPress Pro plugin for WordPress is vulnerable to Authentication Bypass via the GitHub OAuth callback in versions up to, and including, 6.2.3. The vulnerability exists in the loginpress on github login() function, which blindly trusts the first element (profile[0]['email']) of the array returned by GitHub's /user/emails endpoint as an account-binding identifier without verifying that the email carries a verified === true status. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by adding an unverified email address matching a local account to their GitHub profile and triggering the OAuth callback via a crafted code parameter — causing the plugin to call get user by('email', ...) and establish an authenticated session for the matched account. Practical exploitation is conditional on GitHub returning the attacker-added unverified email at index 0 of the /user/emails response, as GitHub typically prioritizes the primary verified address first; nonetheless, the absence of any email verification check in the plugin constitutes a fundamental authentication bypass flaw.
