Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
cloudfunctions/execute
Google Cloud Functions Execution
What an attacker could do
A publicly executable Google Cloud Function lets attackers run it at will, abusing its service account permissions to reach GCP resources and incurring uncontrolled invocation costs.
How to defend it
Disable unauthenticated invocation, require IAM-based auth (Cloud Run/Functions invoker role), and grant the function's service account least-privilege scopes.
