Hi @Bhanu31 ,
Certainly! Here's the explanation for the property `com.glide.security.check_unsanitized_html` and its impact, along with the list of disallowed HTML tags after setting the property to 'enforce':
### 1) **Explanation of `com.glide.security.check_unsanitized_html`:**
The property `com.glide.security.check_unsanitized_html` is a security setting in ServiceNow that controls whether the system checks for unsanitized HTML content in fields. When this property is set to `'enforce'`, ServiceNow checks for unsafe HTML content and sanitizes it to prevent potential security vulnerabilities.
### 2) **List of Disallowed HTML Tags (After Setting to 'Enforce'):**
When `com.glide.security.check_unsanitized_html` is set to `'enforce'`, ServiceNow disallows certain HTML tags and attributes to prevent security risks. The exact list of disallowed tags and attributes may vary based on the ServiceNow version and patch level, as security policies and restrictions might be updated in newer releases. Generally, common disallowed tags include `<script>`, `<iframe>`, `<object>`, and other tags that can execute scripts or load external content.
To get the most accurate and up-to-date information about the disallowed tags in your specific ServiceNow version, you should refer to the official ServiceNow documentation, security advisories, or contact ServiceNow support.
### 3) **Deleting the Property (`com.glide.security.check_unsanitized_html`):**
In standard configurations, you cannot delete system properties in ServiceNow. Deleting core system properties can lead to unpredictable behavior and security vulnerabilities. It's highly discouraged to delete or modify fundamental security properties.
Instead, if you need to revert to the default behavior or change the setting, you can reset the property to its default value. To reset the property, go to "System Properties" in your ServiceNow instance, find the property `com.glide.security.check_unsanitized_html`, and reset it to its default value.
Remember, when dealing with security-related settings, always follow best practices, and consider the implications of your changes to maintain the integrity and security of your ServiceNow instance.
