The Login with Phone Number WordPress Plugin, version < 1.4.2, is affected by an authenticated SQL injection vulnerability in the 'ID' parameter of its 'lwpforgotpassword' action.

The Login with phone number WordPress plugin before 1.3.8 does not sanitise and escape plugin settings which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed.

The Login with phone number WordPress plugin before 1.3.7 includes a file delete.php with no form of authentication or authorization checks placed in the plugin directory, allowing unauthenticated user to remotely delete the plugin files leading to a potential Denial of Service situation.
