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 1.3.7 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.

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.
