Summary
The login-social WordPress plugin through 1.0.4 does not validate password-reset requests against a reset key or the requester's identity, and it issues authentication sessions from unverified third-party sign-in data, allowing unauthenticated attackers to reset any user's password or log in as any existing account, including administrators, and take over the site.
