AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Live Composer – Free WordPress Website Builder plugin. It occurs due to insufficient input sanitization and output escaping on user-supplied attributes, allowing authenticated users with Contributor-level access or higher to inject arbitrary web scripts. These scripts then execute whenever any user accesses the injected page.
How can this vulnerability impact me? :
The vulnerability can allow attackers with Contributor-level access or above to inject malicious scripts into pages. These scripts execute in the context of users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions that compromise user data and site integrity.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should update the Live Composer – Free WordPress Website Builder plugin to version 2.0.3 or later, as this version was released shortly after the vulnerability disclosure and likely contains security fixes addressing the issue. [3]
