CVE-2025-2749
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 authenticated remote code execution in Kentico Xperience allows authenticated users Staging Sync Server to upload arbitrary data to path relative locations. This results in path traversal and arbitrary file upload, including content that can be executed server side leading to remote code execution.This issue affects Kentico 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 confidenceAuthenticated users with Staging Sync Server access can exploit a path traversal vulnerability to upload arbitrary files to relative locations in Kentico Xperience versions through 13.0.178. The uploaded content can be executed server-side, achieving remote code execution.

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.
-
Identify Kentico Xpresence installationSearch for Kentico Xperience installation directories or check installed programs on the server. Look for CMS folders, Kentico directories, or the kentico service executable.Affected if Kentico Xperience software is found on the system
-
Check installed Xperience versionLocate the version information in the Kentico installation, typically found in the CMS or administration interface under 'About' or 'Version' information, or check assembly version of Kentico DLLs in the bin folder.Affected if The installed version is 13.0.178 or lower
-
Determine if Staging Sync Server is enabledCheck Kentico Xperience configuration settings for Staging Sync Server. This is typically configured in the Kentico administration settings, web.config, or the synchronization settings panel.Affected if Staging Sync Server feature is enabled or configured on the instance
-
Verify user access to Staging Sync functionalityReview user roles and permissions in Kentico Xperience admin panel, specifically checking which users or roles have staging/synchronization upload permissions.Affected if There are authenticated users with staging upload permissions, especially users outside minimal trusted administrator group
-
Inspect recent staging synchronization activityReview Kentico staging sync logs, server access logs, and file system for any recent file uploads to unexpected directories via the staging sync mechanism.Affected if There are file write operations to non-standard directories or any evidence of path traversal in staging sync logs
A user is affected if they have Kentico Xperience version 13.0.178 or lower with Staging Sync Server enabled and authenticated users who can access the staging sync upload functionality.

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 vendor patch when available; restrict Staging Sync Server permissions to only trusted authenticated users and implement strict path validation on file upload operations in the staging module.
