Technical details
A cross-site scripting vulnerability exists in GitLab's syntax highlighting output due to improper sanitization of HTML attributes. An authenticated user can craft a malicious repository that, when syntax-highlighted and viewed by other users, executes arbitrary JavaScript in their browser context. The attack requires user interaction (viewing the repository) and prior authentication by the attacker.
