CVE-2026-21721

Executive Summary

The Dashboard Permissions Scope Bypass Enables Cross-Dashboard Privilege Escalation vulnerability poses a significant threat to an organization's internal security, with a high likelihood of exploitation and potential business impact. This vulnerability could be exploited by an internal actor to gain unauthorized access and control over sensitive information and capabilities. The overall risk is heightened due to the ease of exploitation and potential for widespread access.

The dashboard permissions API is vulnerable to a scope bypass issue, allowing users with permission management rights on one dashboard to access and modify permissions on other dashboards. This occurs because the API only checks for the dashboards.permissions:* action and fails to verify the target dashboard scope. As a result, an attacker can exploit this vulnerability to escalate their privileges within an organization, potentially gaining access to sensitive information and capabilities. The attack vector for this vulnerability involves an internal actor with existing permission management rights on at least one dashboard, who can then leverage this vulnerability to expand their access and control across other dashboards. The potential impact of this vulnerability is significant, as it could allow an attacker to compromise the security and integrity of an organization's dashboard infrastructure, potentially leading to unauthorized data access, modification, or deletion.

Exploitation Context

A realistic exploitation scenario involves an insider threat, such as a disgruntled employee or a malicious administrator, who uses their existing permission management rights to exploit the vulnerability and gain access to other dashboards, potentially compromising sensitive information and capabilities. The motivation for an attacker to exploit this vulnerability is to gain unauthorized access and control, potentially for financial gain, to disrupt operations, or to exfiltrate sensitive data.

Patch Priority

Recommended Actions

• Apply the recommended patch or update to the dashboard permissions API as soon as possible
• Conduct a thorough review of dashboard permissions and access controls to ensure they are up-to-date and aligned with organizational policies
• Implement additional security measures, such as multi-factor authentication and monitoring of dashboard activity, to detect and prevent potential exploitation
