CWE-1220
Insufficient Granularity of Access Control
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.

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.

Title
Keycloak: org.keycloak.authorization: keycloak: information disclosure via broken access control in user lookup endpoint
Summary
A flaw was found in Keycloak. A broken access control vulnerability in the Account Resources user lookup endpoint allows a remote authenticated user, who owns at least one User-Managed Access (UMA) resource, to enumerate and harvest personally identifiable information (PII) for all realm users. By sending crafted requests with arbitrary usernames or email values, the endpoint returns full profile objects for unrelated users. This leads to broad profile-level information disclosure.

CVE-2026-38743 (GCVE-0-2026-38743)
Vulnerability from cvelistv5 – Published: 2026-04-24 12:36 – Updated: 2026-04-24 16:20

Title
Apache Airflow: Dags endpoint might provide access to otherwise inaccessible entities
Summary
The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts (including their request parameters) and full TaskInstance details for DAGs outside their authorized scope. Because HITL prompts and TaskInstance fields routinely carry operator parameters and free-form context attached to a task, the leak widens visibility of DAG-run data beyond the intended per-DAG RBAC boundary for every authenticated user.
Users are recommended to upgrade to version 3.2.1 , which fixes this issue.
Severity
No CVSS data available.

Apache Airflow: Assets graph view bypasses DAG level access control displaying unrelated topologies and all DAGs names to unauthorized users
Summary
The asset dependency graph did not restrict nodes by the viewer's DAG read permissions: a user with read access to at least one DAG could browse the asset graph for any other asset in the deployment and learn the existence and names of DAGs and assets outside their authorized scope.
Users are recommended to upgrade to version 3.2.1, which fixes this issue.

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.

Mitigation
Phases: Architecture and Design, Implementation, Testing
Description:
- 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.
