Description
The package cookiecutter before 2.1.1 are vulnerable to Command Injection via hg argument injection. When calling the cookiecutter function from Python code with the checkout parameter, it is passed to the hg checkout command in a way that additional flags can be set. The additional flags can be used to perform a command injection.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cookiecutter, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update cookiecutter to 2.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24065 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
