CVE-2023-26546Network attack vector

Authenticated code execution via crafted template file

Published May 2, 2023 · Updated Jan 30, 2025

Server-side template injection in ECHA IUCLID before 6.27.6 allows remote authenticated users to execute arbitrary code through a crafted template file. The template-processing component interprets attacker-supplied template directives as executable server-side code instead of treating them solely as template content. Exploitation requires template manager permission and permits arbitrary code execution within the affected IUCLID deployment.
