The vulnerability can lead to high confidentiality and integrity impacts by allowing attackers to execute malicious scripts within GitLab, potentially stealing sensitive information or manipulating data. It requires low privileges and user interaction but can have significant consequences for affected users.

Mitigation Strategies

To mitigate this vulnerability, you should immediately upgrade your GitLab CE/EE installations to the patched versions 18.5.5, 18.6.3, or 18.7.1 or later. These versions address the stored cross-site scripting issue caused by GitLab Flavored Markdown. Applying these updates will protect your system from exploitation. [1]
