Enable HTML Sanitizer within Virtual Agent
Use the com.glide.cs.html.sanitizer.enabled property to enable HTMLSanitizerService.
The com.glide.cs.html.sanitizer.enabled system property controls the whether the HtmlSanitizerService is enabled. If com.glide.cs.html.sanitizer.enabled is not set to true, then a Stored Cross-Site Scripting (XSS) attack is possible in the VA web client.
Ensure that the property com.glide.cs.html.sanitizer.enabled is set to true.
Warning: This is a safe harbor property, meaning the value can't be altered once it's changed. It is non-revertible.
