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.

176 vulnerabilities reference this CWE, most recent first.

CVE-2026-20107 (GCVE-0-2026-20107)

Vulnerability from cvelistv5 – Published: 2026-02-25 16:14 – Updated: 2026-02-25 19:05

Title
Cisco Application Policy Infrastructure Controller Denial of Service Vulnerability
Summary
A vulnerability in the Object Model CLI component of Cisco Application Policy Infrastructure Controller (APIC) could allow an authenticated, local attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. To exploit this vulnerability, the attacker must have valid user credentials and any role that includes CLI access. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by issuing crafted commands at the CLI prompt. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

CVE-2026-14615 (GCVE-0-2026-14615)

Vulnerability from cvelistv5 – Published: 2026-07-03 15:47 – Updated: 2026-07-13 11:46
VLAI
Title
Keycloak-services: keycloak: fgap v2 parent group children endpoint bypasses per-child view permission filter
Summary
A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes.

Title
Keycloak: keycloak: information disclosure due to user profile permission bypass
Summary
A flaw was found in org.keycloak.services. An administrator with delegated access to read group memberships and users can bypass user profile permissions by accessing the group members endpoint. This allows the administrator to view user attributes that are explicitly configured to be denied, leading to information disclosure.

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.

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.
