CVE-2022-2455Network attack vector

Authenticated service interruption via malicious project import

Published Oct 17, 2022 · Updated May 13, 2025

Resource exhaustion in GitLab CE/EE affected releases allows remote authenticated users to interrupt service by importing a malicious project. GitLab attributes the flaw to business logic for large repositories, but the public record does not identify the faulty function or specific resource-accounting operation. The user must be authenticated and authorized to import a crafted project; the bounded consequence is exhaustion of server resources and resulting service interruption.
