An issue was discovered in GitLab CE/EE affecting all versions starting from 17.2 prior to 17.3.7, starting from 17.4 prior to 17.4.4 and starting from 17.5 prior to 17.5.2, which could have allowed an attacker gaining full API access as the victim via the Device OAuth flow.
Solution:
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.
