A denial of service (DoS) condition was discovered in GitLab CE/EE affecting all versions from 13.2.4 before 17.4.5, 17.5 before 17.5.3, and 17.6 before 17.6.1. By leveraging this vulnerability an attacker could create a DoS condition by sending crafted API calls. This was a regression of an earlier patch.
Weakness
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.
