Description

A field of a form built with Sitecore Forms might get submitted without a value. The issue occurs in the following scenarios:

• Fields with applied validation (for example, set to Mandatory) might be bypassed by deleting the related input in the HTML markup.
• Fields with applied validation might be bypassed by modifying the related input in the HTML markup.

Solution

To resolve the issue, consider one of the following options:

• Upgrade the Sitecore XP instance to Sitecore XP 10.2.1 or later.
• For Sitecore XP 10.2.0, download and install the latest cumulative hotfix as specified in KB1001439.
• For Sitecore XP 9.3, download and install the hotfix: SC Hotfix 466419-1.zip.

  Be aware that the hotfix was built for the specific Sitecore XP version and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.

  Note that the ZIP file contents must be extracted to locate installation instructions and related files inside. The hotfix must be installed on a CM instance and then synced with other instances using standard development practices.

• For Sitecore XP 9.1.1, download and install the corresponding cumulative hotfix available in KB1001330.
