GitLab authentication tokens facilitate several critical functions:

• Automating Workflows: They integrate GitLab repositories with tools for version control, testing, and deployment.
• CI/CD Pipelines: Tokens are used to authenticate jobs, fetch code, or deploy applications securely.
• Limited Access Control: Tokens are scoped, meaning they can grant permission only for specific tasks like reading code or writing to a repository, reducing potential misuse.

3. Risks of Exposed Tokens

Despite their utility, exposed GitLab tokens pose serious risks:

• Unauthorized Access: Malicious actors can misuse exposed tokens to clone repositories, edit code, or even tamper with sensitive projects.
• Data Breaches: If a token is leaked in public forums, such as the Internet Archive, it may lead to a widespread breach of a project’s source code and related secrets.
• Automation Vulnerabilities: Misconfigured CI/CD environments can unintentionally expose tokens, providing attackers a gateway into the system.

Types of GitLab Tokens and Their Uses

To mitigate these risks, it’s essential to regularly rotate tokens, restrict their scope, and use environment variables in CI/CD setups to store them securely​.
