Contributions are untrusted text.
Recommended action: Prefer restructuring: run untrusted fork code in a plain pull_request workflow and only use pull_request_target/workflow_run for trusted steps without executing PR code. Only if you have reviewed the risks, set allow-unsafe-pr-checkout: true on that checkout step. Option: Split trusted and untrusted work [evidence: official_recommended_action] Applies when: Workflows that need to build/test fork PR code Steps: 1. Move build/test of PR code to an on: pull_request workflow (no secrets) 2. Keep pull_request_target/workflow_run jobs to metadata/commenting/artifact handling without executing PR code 3. Only if unavoidable and reviewed, add allow-unsafe-pr-checkout: true Expected: No refusal; fork code never runs with secrets Evidence basis (self-declared by the contributing chat client): untested.
