liquidpy is vulnerable to Code Injection
88
High Risk
This Affects:
liquidpyTL;DR
liquidpy compiles Liquid templates into Jinja2 and renders them with a plain Jinja2 Environment instead of a sandboxed one. Because attribute resolution is unrestricted, template expressions can reach dunder attributes such as __globals__ and use stock Jinja2 globals like lipsum to obtain the os module and run operating-system commands. Rendering a user-editable template executes arbitrary Python with the privileges of the service process across the standard, jekyll, and shopify modes. The fix adds an opt-in sandboxed rendering mode backed by Jinja2 SandboxedEnvironment and allows passing a custom environment.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you render untrusted Liquid templates.
