AI Powered Q&A
Can you explain this vulnerability to me?
The Tuxquote plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) through its 'TUXQUOTE' shortcode in versions up to and including 1.3.
This vulnerability arises because the plugin does not properly sanitize or escape user-supplied attributes such as 'title', 'align', and 'width' in the tuxquote_build_format() function.
As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages, which will execute whenever any user views those pages.
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 execute in the context of users who visit the affected pages, potentially leading to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.
Because the attack is stored, the malicious script persists on the site and affects all visitors to the injected pages.
