What is CVE-2025-9859?

The Fintelligence Calculator plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability through its 'fintelligence-calculator' shortcode. This issue arises due to inadequate input sanitization and output escaping of user-supplied attributes, allowing authenticated attackers with contributor-level access or higher to inject arbitrary web scripts. These scripts may execute on pages viewed by other users, posing significant security risks. Users should update to the latest version and review their plugin settings to mitigate potential attacks.
