Allocation of Resources Without Limits or Throttling in GitLab
Details

A lack of length validation in GitLab CE/EE affecting all versions from 8.3 before 15.10.8, 15.11 before 15.11.7, and 16.0 before 16.0.2 allows an authenticated attacker to create a large Issue description via GraphQL which, when repeatedly requested, saturates CPU usage.
