Description

The package cocoapods-downloader before 1.6.2 are vulnerable to Command Injection via hg argument injection. When calling the download function (when using hg), the url (and/or revision, tag, branch) is passed to the hg clone 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 dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cocoapods-downloader, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update cocoapods-downloader to 1.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-21223 is resolved across your whole dependency graph.

  3. 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.
