Prompt injection turned Google’s Antigravity file search into RCE

Security researchers found a prompt injection flaw (tricking an AI by hiding instructions in its input) in Google's Antigravity IDE that could bypass its Secure Mode sandbox protections and achieve RCE (remote code execution, where an attacker can run commands on a system they don't own). The vulnerability came from insufficient input validation in the file search tool's Pattern parameter, allowing attackers to inject malicious command-line flags that converted a simple file search into arbitrary code execution. Google acknowledged the issue in January and fixed it internally, and Antigravity users are now protected without needing to take action.
