CVE-2019-11872: Incsub Hustle

High severity, CVSS 8.8. EPSS: 2.2% chance of exploitation in the next 30 days.

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.

Affected products

• Incsub Hustle: before 6.0.8.1 (fixed in 6.0.8.1)
