  "summary" : "Giskard has Unsandboxed Jinja2 Template Rendering in ConformityCheck",
  "details" : "## Summary\n \nThe `ConformityCheck` class in `giskard-checks` rendered the `rule` parameter through Jinja2's default `Template()` constructor. Because the `rule` string is silently interpreted as a Jinja2 template, a developer may not realize that template expressions embedded in rule definitions are evaluated at runtime. In a scenario where check definitions are loaded from an untrusted source (e.g. a shared project file or externally contributed configuration), this could lead to arbitrary code execution.\n\n`giskard-checks` is a local developer testing library with no network-facing service. Check definitions, including the `rule` parameter, are provided in application code or project configuration files and executed locally. Exploitation requires write access to a check definition and subsequent execution of the test suite by a developer.\n\nHowever, the implicit template evaluation of the `rule` parameter is not obvious from the API surface. This hidden behavior increases the likelihood of a developer inadvertently passing untrusted input to it when integrating the library into a larger system. \n\n## Affected Component\n \n`conformity.py`, line 59:\n```python\nfrom jinja2 import Template\n...\nformatted_rule = Template(self.rule).render(trace=trace)\n```\n \n## Affected Versions\n \n`giskard-checks` < 1.0.2b1\n \n## Patched Version\n \n`giskard-checks` >= **1.0.2b1** (template parsing removed from rule evaluation entirely)\n \n## Remediation\n \nUpgrade to `giskard-checks` >= 1.0.2b1. The template rendering has been removed from rule evaluation.\n \n## Credit\n \nGiskard-AI thanks @dhabaleshwar for identifying the unsandboxed template usage.",
