Google Looker Bugs Allow Cross-Tenant RCE, Data Exfil
Researchers have identified two significant security issues in Google Looker, a popular business intelligence and data analytics platform used by over 60,000 companies, including Wayfair, Coinbase, and Walmart. The vulnerabilities, which include a remote code execution (RCE) chain and a SQL injection vulnerability, could allow attackers to access sensitive data and gain access to other tenants’ environments on the Google Cloud Platform (GCP).
Why This Matters
The technical reality of cloud-based data analytics platforms like Google Looker is that they often have complex architectures and multiple dependencies, making them vulnerable to security issues. Ideal models of security assume that all components are secure and up-to-date, but in reality, vulnerabilities like the ones found in Google Looker can have significant consequences, including data exfiltration and lateral movement. The cost of such vulnerabilities can be high, with the potential for damage to reputation, financial loss, and regulatory penalties.
Key Insights
- CVE-2025-12743: A mid-grade SQL injection vulnerability in Google Looker’s internal database, earning a CVSS rating of 6.0 out of 10.
- Path traversal and Git hook manipulation: Techniques used by researchers to develop an exploit chain for RCE in Google Looker.
- Principle of least privilege: A security best practice that organizations should follow to isolate high-risk assets like Google Looker and prevent lateral movement.
Working Example
No code example is provided for this article, as the vulnerabilities discussed are specific to Google Looker and require a detailed understanding of the platform’s architecture and dependencies.
Practical Applications
- Use Case: Companies like Wayfair, Coinbase, and Walmart use Google Looker for business intelligence and data analytics, and should prioritize patching and securing their instances to prevent vulnerabilities like the ones discussed.
- Pitfall: Organizations that delay updating or patching their Google Looker instances may be vulnerable to attacks, highlighting the importance of regular security audits and updates.
