AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Ivory Search WordPress plugin. It occurs due to insufficient input sanitization and output escaping in the admin settings, allowing authenticated users with administrator-level permissions or higher to inject malicious web scripts. These scripts execute whenever a user accesses the affected page. It specifically affects multi-site installations and installations where the unfiltered_html setting is disabled.
How can this vulnerability impact me? :
An attacker with administrator-level permissions can inject malicious scripts that execute in the context of users visiting the injected pages. This can lead to unauthorized actions, data theft, session hijacking, or other malicious activities within the affected WordPress multi-site environment.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, update the Ivory Search – WordPress Search Plugin to a version later than 5.5.13 where the issue is fixed. Additionally, ensure that only trusted administrators have access to the plugin settings, and consider enabling unfiltered_html if appropriate for your environment. Since the vulnerability affects multi-site installations, review and secure all sites accordingly.
