ChatGPT for Google Sheets Vulnerable to Data Exfiltration

How Secure is Your Workbook?

A popular productivity tool that integrates ChatGPT with Google Sheets has been found vulnerable to data exfiltration and phishing attacks. The vulnerability affects workbooks across a victim's account after a single sheet is compromised. This has raised concerns among users who rely on the tool for data analysis.

The vulnerability occurs when an indirect prompt injection is made in a single sheet, allowing attackers to access and exfiltrate data from other sheets within the same account. This is possible because ChatGPT for Google Sheets has access to the entire workbook, not just the specific sheet where the prompt is injected.

When a user installs ChatGPT for Google Sheets, they grant the add-on permission to access their Google Sheets data. If an attacker can inject a malicious prompt into a sheet, they can potentially access sensitive data stored in other sheets within the same workbook.

Can AI-Powered Tools be Trusted?

The vulnerability highlights the risks associated with using AI-powered productivity tools that have broad access to user data. As these tools become more prevalent, the potential attack surface expands, making it essential for users to be cautious when granting permissions.

The discovery of this vulnerability raises questions about the security of AI-powered productivity tools. As users increasingly rely on these tools to streamline their workflows, it is crucial to ensure that they are designed with robust security measures to prevent data breaches.

The consequences of this vulnerability are significant, as it could lead to unauthorized access to sensitive data. Users must be aware of the risks and take steps to mitigate them, such as limiting the permissions granted to AI-powered add-ons.
