Released: May 15, 2024

Survey Now v1.10.4 contains an important fix of a security vulnerability, implements a capability to filter values used in built-in calculation functions within expressions (sumInArray, avgInArray, countInArray, etc.), and includes other bug fixes and minor enhancements.

In previous releases, the imageLink property of an Image question accepts and executes JavaScript code when the contentMode is set to "youtube". This security vulnerability enables an attacker to create a survey JSON schema with malicious code injected into it and execute this code on a victim's device when running the survey. Survey Now v1.10.4 fixes this vulnerability. Please migrate to the latest Survey Now version if you use Form Library or Survey Creator in your application.

Expressions support a number of built-in functions used to perform calculations within a survey JSON schema. Such functions as sumInArray, maxInArray, minInArray, avgInArray, and countInArray aggregate data in an array that contains a response to a Single- or Multi-Select Matrix, Dynamic Matrix, or Dynamic Panel question. Since Survey Now v1.10.4, these functions have a third (optional) parameter—filter—which is an expression that defines a rule according to which values are included in the calculation. For instance, the code below finds a minimum value within a "quantity" matrix column. The expression passed as the third parameter imposes additional conditions: include only positive values and search for the minimum value only in the rows with a "categoryId" column equaling 1.

"expression": "minInArray({matrixdynamic}, 'quantity', {quantity} > 0 and {categoryId} = 1)"
