High CVSS 8.5
CVE-2026-19228
GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.1.4 and 19.2 before 19.2.2 that under certain conditions could have allowed an authenticated user to cause AI usage to be attributed to another namespace, due to improper authorization of identity information supplied in requests.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can modify or destroy data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Changing an identifier in the request grants access to another user’s data.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
