CVE-2026-2334Network attack vector

Admin RCE via unchecked CSV upload

Published Aug 20, 2026 · Updated Aug 20, 2026

Arbitrary file upload in vsDesk 14.0101 allows remote authenticated administrators to execute code via the Import via CSV feature. The Import via CSV handler relies on client-side file checks and lacked server-side validation of uploaded content, allowing a non-CSV file to be accepted and placed into a path where the web application could execute it. Exploitation requires administrative access, and the published record bounds the consequence to code execution in the web application's execution context.
