CVE-2023-36429Network attack vector

Authenticated information disclosure via XPath injection

Published Oct 10, 2023 · Updated Apr 14, 2025

XPath injection in Microsoft Dynamics 365 (on-premises) before 9.0.50.03 or 9.1.22.04 allows remote authenticated users to read sensitive data. Microsoft identifies improper neutralization within XPath expressions but does not disclose the affected endpoint, query, or how untrusted input reaches it. Low-privilege credentials and network access are required; the reported consequence is unauthorized information disclosure without data modification or service interruption.
