This vulnerability is moderately dangerous and expected to become exploited.
Note that this affects the "Professional" version of the plugin. Since both free and premium versions use the same slug and title, there is no distinction between the two.
This could allow a malicious actor to inject malicious scripts, such as redirects, advertisements, and other HTML payloads into your website which will be executed when guests visit your site.
CVSS score is a way to evaluate and rank reported vulnerabilities in a standardized and repeatable way but which is not ideal for WordPress.
We advise to mitigate or resolve the vulnerability immediately.
Patchstack has issued a mitigation rule to block any attacks until you have updated to a fixed version.
