Technical description

The Hustle (aka wordpress-popup) plugin 6.0.7 for WordPress is vulnerable to CSV Injection as it allows for injecting malicious code into a pop-up window. Successful exploitation grants an attacker with a right to execute malicious code on the administrator's computer through Excel functions as the plugin does not sanitize the user's input and allows insertion of any text.

NVD vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
