This security measure protects against malicious code execution in preview deployments. Only trusted collaborators should have the ability to trigger deployments.

🛡️ Learn more about this security feature

This protection prevents unauthorized users from:

• Executing malicious code on the deployment server
• Accessing environment variables and secrets
• Potentially compromising the infrastructure

Preview deployments are powerful but require trust. Only users with repository write access can trigger them.
