CVE-2025-2747
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn authentication bypass vulnerability in Kentico Xperience allows authentication bypass via the Staging Sync Server component password handling for the server defined None type. Authentication bypass allows an attacker to control administrative objects.This issue affects Xperience through 13.0.178.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceKentico Xperience contains an authentication bypass vulnerability in the Staging Sync Server component where improper password handling for servers defined with 'None' type allows attackers to bypass authentication and gain administrative control over the CMS.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Kentico Xperience versionLocate the installed Kentico Xperience version number in the system (typically found in the administration interface under About, or in assembly metadata)Affected if The installed version is 13.0.178 or any version lower than 13.0.178
-
Verify Staging Sync Server is enabledAccess the Staging configuration in Kentico Xperience admin (Modules > Staging) or check for staging-related configuration in the CMS_STAGING or similar staging tables in the databaseAffected if Staging Sync Server is configured and active in the environment
-
Identify staging servers with 'None' authentication typeQuery the staging server configuration (look for server records in the database staging tables or via the admin UI) and check the authentication type setting for each configured staging serverAffected if Any staging server is configured with authentication type set to 'None' (or no authentication/password not required)
-
Check staging endpoint accessibilityDetermine if staging sync endpoints are exposed externally or on accessible network segments (typically paths under /CMSModules/Staging or similar staging URL routes)Affected if Staging sync endpoints are reachable from untrusted networks without additional authentication controls
The environment is affected if running Kentico Xperience version 13.0.178 or lower AND has staging servers configured with 'None' authentication type that are accessible to attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch/hotfix for Xperience 13.0.178 and review staging server configurations to ensure proper authentication enforcement.
