CVE-2026-41553Network attack vector

Unauthenticated code execution via unsanitized export data

Published May 15, 2026 · Updated May 15, 2026

OS command injection in DHTMLX PDF Export Module 0.3.3 through 0.7.5 allows remote attackers to execute code through crafted export data. The export service passes an unsanitized data parameter to Node.js, which executes attacker-supplied JavaScript rather than treating it only as export content. No authentication or user interaction is required, and successful exploitation compromises the server under the module's process privileges.
