Common Weakness Enumeration

CWE-1220

Allowed

Insufficient Granularity of Access Control

Abstraction: Base · Status: Incomplete

API response cwe.mitre.org

The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.

125 vulnerabilities reference this CWE, most recent first.

Insufficient Granularity of Access Control in GitLab
Summary
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.11 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user with a project-scoped fine-grained Personal Access Token to permanently delete or modify group-level labels, due to incorrect authorization logic on label ownership scope validation.

CVE-2026-6388 (GCVE-0-2026-6388)

Vulnerability from cvelistv5 – Published: 2026-04-15 21:34 – Updated: 2026-07-15 00:41

Title
Argocd-image-updater: argocd image updater: cross-namespace privilege escalation via insufficient namespace validation
Summary
A flaw was found in ArgoCD Image Updater. This vulnerability allows an attacker, with permissions to create or modify an ImageUpdater resource in a multi-tenant environment, to bypass namespace boundaries. By exploiting insufficient validation, the attacker can trigger unauthorized image updates on applications managed by other tenants. This leads to cross-namespace privilege escalation, impacting application integrity through unauthorized application updates.

CVE-2025-31938 (GCVE-0-2025-31938)

Vulnerability from cvelistv5 – Published: 2026-08-11 16:28 – Updated: 2026-08-12 13:39
VLAI
Summary
Insufficient granularity of access control in some subsystem for some Intel(R) Xeon(R) 6 Scalable processors with Intel(R) TDX may allow an information disclosure. Authorized adversary with an authenticated user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.

Mitigation
Architecture and Design Implementation Testing
  • Access-control-policy protections must be reviewed for design inconsistency and common weaknesses.
  • Access-control-policy definition and programming flow must be tested in pre-silicon, post-silicon testing.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.

CAPEC-180: Exploiting Incorrectly Configured Access Control Security Levels

An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
