This vulnerability enables the injection of malicious Jinja template syntax, potentially leading to arbitrary code execution with server process privileges. Organizations using Skyvern should prioritize patching to mitigate the risk of unauthorized access and control over their server environments.

Original NVD Description

Skyvern before 1.0.45 contains a sandbox escape vulnerability in TextPromptBlock that renders prompts twice, first through a sandboxed Jinja environment and then through an unsandboxed environment. Attackers can inject malicious Jinja template syntax through workflow parameters or upstream block output to execute arbitrary code with server process privileges.
