- Under **Context Security**, you can select an option from the **Invalid Content Policy** dropdown menu.
- The default option in this menu is **Warn and Auto-Clean Invalid Content**, however, there are other options in this menu.
- It is possible that while you are navigating around ClearPoint, you come across a red message that states: “Warning: Invalid or potentially dangerous content was filtered out of this field. Please contact [support@clearpointstrategy.com](mailto:support@clearpointstrategy.com) for more information.”
- This message indicates that the field’s HTML has potential for cross-site scripting, a security vulnerability allowing a user to alter the code that an application delivers to a user which is executed in the user’s web browser. We implemented a tool that searches for this vulnerable HTML and auto cleans it.
- The Invalid Content Policy dropdown menu controls the options on this tool.
- For more information about this, feel free to read [this article](https://jsoup.org/cookbook/cleaning-html/whitelist-sanitizer) that explains how we approached preventing cross-site scripting.
