Summary

An XSS vulnerability has been identified in the gitlab-web-ide-vscode-fork component that allows an attacker to execute malicious scripts in a user's browser. This issue primarily affects all versions prior to 1.89.1-1.0.0-dev-20241118094343 within the GitLab environment. Specifically, it can occur when loading Jupyter notebook (.ipynb) files in the GitLab web IDE, impacting GitLab CE/EE versions from 15.11 to 17.3 and temporarily affecting subsequent versions (17.4, 17.5, and 17.6). As a result, this flaw exploits the web IDE component, presenting potential security risks for users who handle notebook files.
