Denial of Service Vulnerability in GitLab by GitLab Inc.

CVE-2025-13927

What is CVE-2025-13927?

CVE-2025-13927 is a denial of service (DoS) vulnerability affecting GitLab, a widely used platform for version control and collaboration in software development. GitLab serves as a repository manager that provides a web-based interface for managing Git repositories, facilitating code review, and enabling continuous integration and deployment. This specific vulnerability allows an unauthenticated user to induce a denial of service condition by sending specially crafted requests with malformed authentication data to the GitLab server. Such an attack could potentially render the application unavailable, disrupting development workflows and impacting productivity within organizations that rely heavily on GitLab for their software development processes.

Potential Impact of CVE-2025-13927

1. Service Disruption: Organizations utilizing GitLab may experience unavailability, hindering their development processes and leading to operational delays. This could affect teams' ability to push updates, manage code repositories, and collaborate effectively.

2. Increased Repair Costs: Recovering from a denial of service attack often involves significant financial resources. Organizations may incur costs associated with mitigating the attack, restoring services, and implementing preventive measures to secure their systems in the future.

3. Reputation Damage: Frequent service outages can damage the reputation of an organization, leading to diminished trust among clients, stakeholders, and partners. This erosion of confidence may result in lost business opportunities and further scrutiny of the organization's cybersecurity practices.
