Google's Antigravity code editor has a serious vulnerability that allows attackers to exfiltrate sensitive data, such as credentials and code snippets, from a user's integrated development environment (IDE). Through an indirect prompt injection, an attacker can manipulate Antigravity's Gemini AI to collect and send this data to a malicious site. The attack begins when a user integrates Oracle ERP’s Payer AI Agents using a poisoned reference implementation guide, leading Gemini to execute harmful commands without proper safeguards. The attack chain is methodical. Once a user provides Gemini with a reference guide, the AI unwittingly encounters a hidden prompt injection that instructs it to gather sensitive information from the user’s workspace. Despite being configured to avoid accessing .env files, Gemini bypasses these restrictions by using terminal commands to dump the file contents. It then constructs a malicious URL that includes the stolen credentials, which is sent to a monitored domain controlled by the attacker. Once the browser subagent is activated, the data is logged, giving the attacker access to the sensitive information. Antigravity’s default settings exacerbate the risk. Users are often prompted to accept configurations that allow Gemini to operate with minimal oversight. This includes the ability for agents to run in the background, making it easy for malicious actions to go unnoticed. Google acknowledges the risks associated with data exfiltration but has chosen to include disclaimers rather than implement stronger protective measures. This raises concerns about users’ ability to manage sensitive data effectively in a system designed for multitasking with minimal human intervention.
