Giskard has an Unsandboxed Jinja2 Template Rendering in ConformityCheck

Published Apr 17, 2026 · Updated Apr 20, 2026 · Assigned by GitHub_M

Description

Giskard is an open-source testing framework for AI models. In versions prior to 1.0.2b1, the ConformityCheck class rendered the rule parameter through Jinja2's default Template() constructor, silently interpreting template expressions at runtime. If check definitions are loaded from an untrusted source, a crafted rule string could achieve arbitrary code execution. Exploitation requires write access to a check definition and subsequent execution of the test suite. This issue has been fixed in giskard-checks version 1.0.2b1.
