GitLab has remediated an issue in GitLab CE/EE affecting all versions from 9.1 before 18.11.7, 19.0 before 19.0.4, and 19.1 before 19.1.2 that under certain conditions could have allowed an unauthenticated user to determine the existence of a private project due to improper authorization controls on cross-project reference pages.
AnalysisAI
Private project existence disclosure in GitLab CE/EE (versions 9.1 through 18.11.x, 19.0.x, and 19.1.x) enables low-privilege GitLab account holders to confirm whether a private project exists via improperly authorized cross-project reference pages. The flaw stems from missing authorization controls (CWE-862) on reference resolution endpoints, leaking project existence metadata to users who have no authorized access to the targeted private project. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires possession of a valid GitLab account with at least the ability to view cross-project reference pages on any project on the target instance (CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N reflects a low-complexity, network-accessible information disclosure requiring low-privilege credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker holding any valid GitLab account on a target self-managed instance sends requests to cross-project reference endpoints targeting suspected private project paths (e.g., enumerating known organizational naming patterns). By comparing response behavior - such as whether a reference renders a project link versus returns a generic not-found state - the attacker builds a list of confirmed private project namespaces and names without accessing any project content. … |
| Remediation | Upgrade to one of the patched releases per your current major version: GitLab CE/EE 18.11.7, 19.0.4, or 19.1.2. … Detailed patch versions, workarounds, and compensating controls in full report. |
