Application Validation

Security framework upgrade

At Zoho Creator, one of our top priorities is to ensure that the data of our customers are safe and secure. We are committed to providing the highest level of security and have been upgrading our systems to ensure we are processing on the latest and most secure protocols. Currently we are upgrading our security framework that is being used to process the user's HTML content.

All HTML content present in the forms, reports, and pages across the application will be checked for the following characteristics:

  1. Invalid HTML tags - Only the standard W3C tags will be permitted. User errors in HTML tags will be handled as per browser behavior.
  2. Invalid styles - Only standard CSS properties will be permitted.
  3. Script rejection -  Javascript content/coded or Javascript related parameters in HTML attribute or values will be removed.
  4. Custom attributes - Only standard attributes for the particular HTML tags will be rendered. User defined attributes will not be rendered. Note: Since attributes can be misused it is recommended to use the  class and id instead.
This upgraded security framework may cause some changes in the behavior of the Zoho Creator application. To ensure a flawless transition, the owner of the application should check for elements incompatible with the new security framework.


The Field display name and field description will be rendered after checking for the above four characteristics.

Form data in Reports:

In reports the HTML tags present in form data of various fields should be checked. There are two ways by which the new security framework will process different field types :

  1. All HTML tags will be displayed as plain text. The fields under this category are: Single line, Multi Line, Email, Drop down/ Radio, Checkbox/ Multiselect, Decision box, users and integration.
  2. The content will be displayed after applying the four common characteristics (Invalid HTML tags, Invalid styles, Script rejection and Custom attributes) mentioned at the top.  The fields under this category are: URL, Image, Signature,Formula, File Upload, Audio and Video.


All content in the page will be rendered after applying the four common characteristics (Invalid HTML tags, Invalid styles, Script rejection and Custom attributes). And any discrepancies to page layout should be checked. 


  • OpenURL tasks with public embed components( will not be permitted to access or do any action in the parent window.
  • The security update will prevent iframe content from using browser plugins. Instead you can use embed tag(<embed>) to render the external PDF content in html.
This update will be automatically rolled out later to all users.
