## Technical details

A deserialization of untrusted data vulnerability in the JavaScript Task component allows an authenticated user with standard permissions to craft a malicious script that achieves remote code execution on shared production infrastructure. The attack requires authentication and user-controlled input (a crafted script), and results in arbitrary code execution with the privileges of the JavaScript Task runtime.
