A cross-site leak vulnerability in the OAuth flow of all versions of GitLab CE/EE since 7.10 allowed an attacker to leak an OAuth access token by getting the victim to visit a malicious page with Safari
Does this matter?
Lower severity and a low EPSS score (1.79%). Track it; it rarely justifies an emergency change on its own.
