Technical details
The plugin fails to properly sanitize user input during web page generation, allowing stored XSS attacks. An attacker with contributor or developer privileges can inject malicious scripts that persist in the database and execute when other users view affected content. Exploitation requires the attacker to have elevated permissions and a user to view the crafted payload.
