Administrators should avoid sending newsletters until a fix is available or implement manual validation and sanitization of input fields to prevent malicious payload injection. Monitoring plugin updates from the vendor is recommended to apply an official fix once released.
Description
The Noptin WordPress plugin up to version 4.4.3 is vulnerable to a Local File Inclusion (LFI) flaw via the 'noptin_fields[first_name]' parameter. This vulnerability allows unauthenticated attackers to include and execute arbitrary PHP files on the server. Exploitation requires an administrator to trigger the sending of a newsletter containing the malicious payload, as unauthenticated users can store PHP code in the first_name field but cannot directly execute it. The vulnerability can lead to code execution, bypassing access controls and potential data exposure.
