AI Powered Q&A
Can you explain this vulnerability to me?
The Sheets2Table plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'titles' shortcode attribute of the [sheets2table-render-table] shortcode in all versions up to 0.4.1.
This vulnerability occurs because the input provided in the 'titles' attribute is not properly sanitized or escaped before being output in the HTML. Specifically, the attribute value is only trimmed of whitespace but then echoed directly inside a table header (<th>) tag without escaping, allowing malicious scripts to be injected.
Authenticated users with Contributor-level access or higher can exploit this to inject arbitrary web scripts that execute whenever a user views the affected page.
How can this vulnerability impact me? :
This vulnerability can allow an attacker with Contributor-level access or above to inject malicious scripts into pages on your WordPress site.
When other users visit these pages, the injected scripts will execute in their browsers, potentially leading to theft of sensitive information, session hijacking, or other malicious actions.
Because the vulnerability is a Stored Cross-Site Scripting issue, the malicious code persists on the site and affects all users who access the compromised content.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
