AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N
Remote unauthenticated path traversal reading server files gives C:H; it is read-only so I:N/A:N; leaked on-disk secrets reach beyond the app, supporting S:C.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 that, under certain conditions, an unauthenticated user could have read arbitrary files from the GitLab server due to improper path confinement and missing authentication enforcement in the repository commits API.

AnalysisAI
Unauthenticated arbitrary file read in GitLab CE/EE lets remote attackers retrieve files from the GitLab server via the repository commits API, which fails to confine paths and does not enforce authentication. All 18.7 releases through 19.3.2 are affected across the fix lines (before 19.1.8, 19.2.6, and 19.3.2). …

Vulnerability AssessmentAI
| Exploitation | Exploitation targets the GitLab repository commits API on self-managed GitLab CE/EE versions 18.7 through the pre-fix releases (before 19.1.8/19.2.6/19.3.2); the vector is AV:N/AC:L/PR:N/UI:N, so no authentication, no user interaction, and network reachability of the GitLab web interface are the only hard requirements. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Every signal points to maximum priority: the CVSS vector is AV:N/AC:L/PR:N/UI:N (remote, low-complexity, unauthenticated, no user interaction), CISA KEV confirms active in-the-wild exploitation, and a public exploit is available on HackerOne (#3909881). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade to GitLab 19.1.8, 19.2.6, or 19.3.2 (or later) depending on your release line - this is the primary and required fix given confirmed active exploitation. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all GitLab CE/EE instances in your environment and determine which are internet-reachable or accessible to untrusted networks; review access logs for exploitation attempts targeting the repository commits API with path traversal patterns. …
