To secure GitHub Actions pull_request_target triggers, enforce minimal permissions and separate untrusted fork testing from privileged operations to prevent privilege escalation and secret leakage.

The best way to secure fork pull requests is implementing a two-stage fork CI pattern that isolates untrusted code testing from privileged deployment operations and restricts secret access.

You can enforce an approval gate for fork deployments by configuring manual approval requirements before deploying fork code and applying restricted environment protections and minimal permissions.

Yes, these secure GitHub Actions trigger patterns apply to pull requests, fork scenarios, and reusable workflows across repositories to mitigate code injection and secret leakage risks.

Workflows leak secrets when misconfigured triggers expose privileged access to untrusted fork code; mitigating this requires explicit context controls and restricted secret access for PR-triggered workflows.

You need to restrict permissions for pull_request triggers when handling untrusted contributions to prevent code injection and ensure safe, auditable patterns for PR-triggered workflows.
