AI Powered Q&A
Can you explain this vulnerability to me?
The Gallagher Website Design plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its login_link shortcode. This vulnerability exists in all versions up to and including 2.6.4 due to insufficient input sanitization and output escaping on the 'prefix' attribute.
Authenticated users with Contributor-level access or higher can exploit this flaw to inject arbitrary web scripts into pages. These injected scripts will execute whenever any user accesses the affected page.
How can this vulnerability impact me? :
This vulnerability allows attackers with Contributor-level access or above to inject malicious scripts into web pages. These scripts can execute in the context of other users visiting the page, potentially leading to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.
Because the vulnerability is a Stored Cross-Site Scripting issue, the malicious code persists on the website and affects all users who view the injected content, increasing the risk and impact.
