Summary
The flaw in UsersWP 1.5.0 to 1.5.9 allows unauthenticated attackers to log in as any user by asserting ownership of an email address through a social login provider, potentially compromising administrator accounts.
Exploitability

NVD description

The UsersWP WordPress plugin before 1.5.10 does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account, allowing unauthenticated attackers to log in as any user, including administrators, whose email address they can assert through a provider account of their own.
