Impact
The vulnerability arises from GitLab's allocation of resources without limits or throttling when processing input from unauthenticated users. This flaw can lead to a denial of service if an attacker sends specially crafted data that bypasses validation and forces the system to consume excessive memory or CPU, thereby disrupting service availability. The weakness is classified as CWE‑770.
Affected Systems
GitLab Community Edition and Enterprise Edition are impacted. Versions from 18.5 up to before 19.0.6, 19.1 before 19.1.4, and 19.2 before 19.2.2 are vulnerable. All other later releases have been remediated.
Risk and Exploitability
The CVSS score is 5.3, indicating moderate severity. EPSS is not available, and the vulnerability is not listed in CISA KEV. Attackers would need to be able to send unauthenticated requests to the affected GitLab instance, likely through the web interface or API, and supply crafted input that triggers uncontrolled allocation. No public exploit has been observed, but the lack of limits means that a successful attack could degrade availability of the entire GitLab service.
