WordPress Plugin Vulnerabilities
MonsterInsights < 8.12.1 - Contributor+ Stored XSS
Description
The plugin does not validate and escape some of its block options before outputting them back in a page/post where the block is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.
Proof of Concept
As a contributor, add an "Inline Popular Posts" to a page/post and put the following payload in the Additional CSS class settings of the block: " onmouseover="alert(/XSS/)" style="background:red;"
