An issue has been discovered in GitLab CE/EE affecting all versions from 9.4 before 17.4.6, 17.5 before 17.5.4, and 17.6 before 17.6.2. An attacker could cause a denial of service with requests for diff files on a commit or merge request.
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
