CVE-2025-6769
Gitlab 15.1.0 – 18.1.6
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-6769 is a medium-severity Exposure of Sensitive System Information to an Unauthorized Control Sphere (CWE-497) vulnerability in Gitlab Gitlab. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique System Information Discovery (T1082); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

V14.1.2
Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.
Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.
Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.
Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.
Protecting environments from unauthorized logical access stops exposure of internal system details to outsiders.
Secure-development practices reduce the chance of code paths that leak sensitive system information.
