An issue was discovered in GitLab CE/EE affecting all versions starting from 15.7 prior to 17.5.5, starting from 17.6 prior to 17.6.3, and starting from 17.7 prior to 17.7.1. It was possible to trigger a DoS by creating cyclic references between epics.
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.
