  "account": "Gitea Actions utilizes runners to execute jobs from various repositories. When a runner registers with a Gitea instance, it establishes a connection and begins receiving work. This registration marks the point at which the platform determines the new execution environment belongs to its CI system. Gitea's documentation provides guidance on registration tokens, which can be passed through a file or environment variable to prevent them from being stored in shell history or process listings. Additionally, Gitea supports ephemeral runners as a hardening option for organization or instance-wide use. These choices are crucial as a runner typically receives source code, job tokens, and deployment credentials. Observations made by ZoomEye on November 9, 2026, at 06:47 Asia/Shanghai indicate the presence of Gitea instances, but these counts do not necessarily reveal information about runner daemons. The phrase \"Act Runner\" found in 76 pages of the data may include documentation but does not prove that any of these runners are open, over-privileged, or capable of executing untrusted code. When registering a runner, it is essential to use an organization or repository registration token to establish the intended boundary. An instance-wide token could potentially enroll a runner that receives jobs from multiple owners. To enhance security, keep the registration token in a secret manager and load it from a protected file or environment variable. Avoid placing the token in a public repository, build log, or command history. After a runner is lost or an administrator changes the configuration, rotate the registration token and revoke the runner's identity. Simply deleting the container without removing the runner record may leave a dormant identity that could be eligible for future work. Limiting what a job can reach is also important. Treat the code supplied by the repository as untrusted unless the organization has implemented a stronger policy. Employ disposable containers or virtual machines, use a non-root user, and restrict the network. Mount only the necessary tools for the job to execute. Separate runners based on trust levels, ensuring that public repositories do not share a runner with production deployment jobs. Job tokens should be scoped to the repository and have a short expiration period, while deployment credentials should only be issued after the job has passed the required review or branch policy. Review labels and routing are also crucial. Runner labels determine which jobs can target an environment, and a label such as \"production\" or \"deploy\" should not be accessible to every repository. Regularly audit who can modify workflow files and which labels those workflows can select. A misrouted job could inadvertently expose secrets to the wrong runner, even if the registration token was managed correctly. It is essential to log runner registration, removal, label changes, and job start events. Set up alerts for new runners originating from unexpected networks or those registered at unusual times. The administrator of the Gitea instance should compare the runner inventory with the deployment system's expected hosts. The registration token is stored separately from source code and logs, and a runner's scope is limited to its designated repository or organization. Public jobs cannot select deployment labels. The filesystem and network of a runner are disposable, and the forge removes a runner as soon as its environment is destroyed. The observed population of Gitea instances is significantly larger than the number revealed by the specific \"Act Runner\" phrase count. This discrepancy provides valuable context: the visible forge does not necessarily reflect the entire fleet of runners operating behind it. Ultimately, managing runner registration as a trust decision, keeping tokens out of process listings, and ensuring that each runner's scope aligns with the code it is permitted to execute are essential steps in maintaining a secure CI environment.",
