CVE-2023-35815Network attack vector

Data-source protection bypass via XML deserialization

Published Apr 28, 2025 · Updated Apr 28, 2025

Deserialization of untrusted XML in DevExpress before 23.1.3 allows attackers to bypass data-source protection through XML data. DevExpress has not published the responsible method or the XML operation that defeats the data-source protection mechanism. MITRE's assessment requires network access and low privileges, while NVD assesses an unauthenticated path; public sources do not resolve the discrepancy or define the resulting data access.
