AI Powered Q&A
Can you explain this vulnerability to me?
The Listen Shortcode plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 1.0. This occurs because the plugin does not properly sanitize or escape user-supplied attributes (src, start, end) in the listenEmbedJS() function. These attributes are echoed inside a single-quoted HTML attribute without escaping, allowing authenticated users with contributor-level access or higher to inject malicious scripts that execute whenever a user views the affected page.
How can this vulnerability impact me? :
This vulnerability can allow attackers with contributor-level access or above to inject arbitrary web scripts into pages. These scripts will execute in the browsers of users who visit the injected pages, potentially leading to theft of user credentials, session hijacking, defacement, or distribution of malware. Because the vulnerability is a Stored Cross-Site Scripting issue, the malicious code persists on the site and affects all visitors to the compromised pages.
