WordPress Plugin Vulnerabilities

WP HTML Author Bio <= 1.2.0 - Author+ Stored Cross-Site Scripting

Description

The plugin does not sanitise the HTML allowed in the Bio of users, allowing them to use malicious JavaScript code, which will be executed when anyone visit a post in the frontend made by such user. As a result, user with a role as low as author could perform Cross-Site Scripting attacks against users, which could potentially lead to privilege escalation when an admin view the related post/s.
