Summary

CVE-2025-34509 is a high-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Sitecore Experience Platform. Its CVSS base score is 7.5 (High).

Operationally, ranked in the top 4.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

Sitecore Experience Manager (XM) and Experience Platform (XP) versions 10.1 through 10.1.4 rev. 011974 PRE, all 10.2 releases, 10.3 through 10.3.3 rev. 011967 PRE, and 10.4 through 10.4.1 rev. 011941 PRE contain a hardcoded user account that permits unauthenticated remote access to an administrative API over HTTP. The flaw is tracked as CWE-798 and carries a CVSS 3.1 score of 7.5 reflecting network-accessible exploitation with no required credentials or user interaction and a direct impact on confidentiality.

An unauthenticated attacker can connect directly to the exposed administrative API using the embedded credentials, obtaining privileged access to management functions without any prior authentication step. This access can be leveraged to read sensitive configuration and data stored within the affected Sitecore instances.

Sitecore’s support article KB1003667 addresses the issue and directs customers to the appropriate patches or configuration changes for the listed versions. Independent analysis published by watchTowr Labs describes the hardcoded account as the initial component of a pre-authentication remote-code-execution chain affecting the Experience Platform.

EPSS for the CVE rose from a low baseline to a recorded peak of 0.2318 before settling at the current value of 0.1687, indicating that exploitation interest increased after public disclosure.
