NewCVE-2025-2746 (opens in a new tab)How to fix?
Upgrade Kentico.Xperience.Libraries to version 13.0.173 or higher.
Overview
Kentico.Xperience.Libraries is a package for libraries and applications that use Kentico Xperience API.
Affected versions of this package are vulnerable to Missing Critical Step in Authentication due to improper handling of empty SHA1 usernames in digest authentication, when the Staging Sync Server is enabled (which it is not by default). An attacker can gain unauthorized access and control over administrative objects by sending malicious requests with empty usernames, which are handled by a Microsoft.Web.Services3 implementation with insufficient verification.
