Can you explain this vulnerability to me?
The Page Builder: Pagelayer plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its Button widget's Custom Attributes field. This vulnerability exists in all versions up to and including 2.0.8. It is caused by an incomplete event handler blocklist in the 'pagelayer_xss_content' XSS filtering function, which blocks some common event handlers but not all. As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages. These scripts execute whenever any user accesses the infected page.
How can this vulnerability impact me? :
This vulnerability allows attackers with Contributor-level access or above to inject arbitrary web scripts into pages. These scripts can execute in the context of any user who views the infected page, potentially leading to unauthorized actions such as stealing session cookies, defacing content, or performing actions on behalf of the user without their consent.
