Summary

CVE-2026-1752 is a medium-severity Incorrect Authorization (CWE-863) vulnerability in Gitlab Gitlab. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); 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 CM-5 (Access Restrictions for Change) — see the control section below for these in your framework.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Improper API authorization (CWE-863) directly allows a developer to perform privileged configuration changes, enabling privilege escalation.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions on API calls so a developer-role user cannot modify protected environment settings.

prevent

Restricts logical access for configuration changes, blocking unauthorized modification of protected environment settings via the API.

prevent

Ensures the developer role is granted only the minimum privileges required, limiting the ability to alter protected environments even if checks are weak.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
