> **`pull_request_target` exception:** When `actions/cache` is used in a `pull_request_target` workflow, the automatic post-step save is **skipped**. This is a security measure to prevent untrusted pull request code from poisoning caches accessible to privileged workflows. If really you need to save a cache in a trusted `pull_request_target` context (e.g., after validating the PR source), use [`actions/cache/save`](./save/README.md) explicitly with an appropriate `if` condition.
