Summary
AI-powered GitHub Actions from companies like OpenAI, Anthropic, and Google have a critical security flaw where prompt injection (tricking an AI by hiding instructions in its input) attacks can be triggered by external attackers, even when configuration settings are meant to restrict access. The vulnerability stems from these actions not properly distinguishing between trusted internal apps and untrusted external apps, allowing anyone to potentially manipulate the AI's behavior through pull requests, issues, or other user-controlled inputs.
