GitLab's Auto-Generated Email Addresses Could Open Door to Supply Chain Attacks

Dark Reading · 24 Sept 2026

Key Takeaway If your business uses GitLab, check how incoming email addresses and their access tokens are managed, and apply any security updates or guidance GitLab provides promptly.

Security researchers have identified a risk in GitLab, a widely used platform for software development and version control. Every user is automatically given an incoming email address, and these addresses contain highly privileged access tokens. If exposed or intercepted, attackers could use these tokens to gain unauthorised access to a user's account and, potentially, the projects and code repositories they manage.

This is particularly concerning for supply chain security. GitLab is often used to store and manage source code that feeds into software products used by many other businesses. If an attacker gains access through a leaked token, they could potentially tamper with code, insert malicious changes, or access sensitive project data, with effects rippling out to anyone using the affected software.

Organisations using GitLab should review how these incoming email addresses are handled, ensure tokens are not exposed in logs, shared emails, or third-party integrations, and follow any guidance issued by GitLab to secure this feature.
