Can you explain this vulnerability to me?
The Dideo plugin for WordPress version 1.0 has a Stored Cross-Site Scripting (XSS) vulnerability. This occurs because the plugin does not properly sanitize or escape the 'id' attribute of its 'dideo' shortcode. The 'id' value is directly inserted into an HTML iframe 'src' attribute without escaping, allowing authenticated users with contributor-level access or higher to inject malicious scripts. These scripts then execute whenever any user views the affected page.
How can this vulnerability impact me? :
This vulnerability can allow attackers with contributor-level access to inject arbitrary web scripts into pages. When other users access these pages, the malicious scripts execute in their browsers. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed in the context of the affected website.
