metricflow is vulnerable to Server-Side Template Injection (SSTI)
88
High Risk
This Affects:
metricflowTL;DR
MetricFlow passes caller or model controlled where_sql_template values to an unsandboxed Jinja environment in both the filter converter and the where filter spec factory. A crafted template runs arbitrary Jinja expressions and reaches Python object internals during query construction, leading to arbitrary code execution via server-side template injection. The fix runs both rendering paths through Jinja's SandboxedEnvironment and rejects templates that raise a SecurityError.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and where_sql_template values can come from untrusted or model-generated input.
Background info
metricflow is vulnerable to Server-Side Template Injection (SSTI) in versions 0.210.0 - 0.212.0.
How to fix this
Upgrade the metricflow library to the patch version.
