CVE-2023-25261Network attack vector

Remote code execution via embedded report source

Published Mar 27, 2023 · Updated Jul 9, 2026

Code injection in Stimulsoft Designer Desktop 2023.1.4 and Designer Web and Viewer Web 2023.1.3 allows remote attackers to execute C# code. Crafted .mrt report files embed C# source, and affected renderers compile that source while restricting selected network libraries but leaving local file-system APIs accessible. An unauthenticated path exists when the host application exposes the embedded designer or viewer without access controls, enabling report-rendering code to read or write server files.
