AI Powered Q&A
Can you explain this vulnerability to me?
The vulnerability exists in the Dealia – Request a Quote plugin for WordPress, affecting all versions up to and including 1.0.6. It is a Stored Cross-Site Scripting (XSS) issue caused by improper output escaping. Specifically, the plugin uses the function wp_kses() for escaping output within HTML attribute contexts where esc_attr() should be used. This flaw allows authenticated users with Contributor-level access or higher to inject malicious web scripts into pages. These scripts execute whenever any user accesses the infected page.
How can this vulnerability impact me? :
This vulnerability can allow attackers with Contributor-level access or above to inject arbitrary scripts into web pages. These scripts can execute in the browsers of users who visit the affected pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions. Because the attack is stored, the malicious code persists and affects all users who view the compromised content.
