Common Weakness Enumeration
CWE-1220
AllowedInsufficient Granularity of Access Control
Abstraction: Base · Status: Incomplete
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.
188 vulnerabilities reference this CWE, most recent first.
CVE-2026-6388 (GCVE-0-2026-6388)

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.

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.

Title
Improper Access Control Granularity impacting Infinera G42
Summary
A missing double-check feature in the WebGUI for CLI deactivation in Infinera G42
version R6.1.3 allows an authenticated administrator to make other
management interfaces unavailable via local and network interfaces. The CLI deactivation via the WebGUI does not only stop CLI interface but deactivates also Linux Shell, WebGUI and Physical Serial Console access. No
confirmation is asked at deactivation time. Loosing access to these services device administrators are at risk of completely loosing device control.

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.
