AI Powered Q&A
Can you explain this vulnerability to me?
The fyyd podcast shortcodes plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 0.3.1.
This vulnerability arises because user-supplied shortcode attributes like 'color', 'podcast_id', and 'podcast_slug' are not properly sanitized or escaped before being inserted into inline JavaScript code.
As a result, an attacker with Contributor-level access or higher can inject malicious scripts that will execute whenever a user views the affected page.
How can this vulnerability impact me? :
This vulnerability can allow an attacker to execute arbitrary JavaScript in the context of the affected website.
Such script execution can lead to theft of user credentials, session hijacking, defacement of the website, or distribution of malware to visitors.
Since the attacker needs Contributor-level access or above, the risk is limited to users with some level of authenticated access, but the impact can still be significant.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
