Name of the Vulnerable Software and Affected Versions ZM Ajax Login & Register plugin for WordPress versions up to, and including, 2.0.2

Description The issue is related to insufficient verification on the user being supplied during a Facebook login through the plugin. This allows unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username.

Recommendations For versions up to, and including, 2.0.2, update to a version later than 2.0.2 to resolve the issue. As a temporary workaround, consider disabling Facebook login through the plugin until a patch is available. Restrict access to administrative accounts to minimize the risk of exploitation.
