Deeper analysis
CVE-2025-2747 is an authentication bypass vulnerability in Kentico Xperience versions through 13.0.178 that resides in the Staging Sync Server component. The flaw stems from improper password handling when a server is configured with the "None" type, allowing an attacker to circumvent authentication controls entirely. It carries a CVSS 3.1 score of 9.8 and is classified under CWE-288.
Unauthenticated remote attackers can exploit the issue over the network without any user interaction or credentials. Successful exploitation grants full control over administrative objects within the affected Xperience instance, enabling arbitrary changes to the CMS environment.
Kentico has published hotfixes addressing the vulnerability through its DevNet portal. Multiple public advisories, including those from VulnCheck and Watchtowr Labs, detail the flaw and reference a proof-of-concept that demonstrates a pre-authentication remote code execution chain. The CVE is also listed in CISA's Known Exploited Vulnerabilities catalog.
The associated EPSS score has reached 0.9141, indicating a high likelihood of exploitation in the wild.
