Summary
During the login process, the server response included a parameter called isMasterAdmin. By intercepting and modifying this parameter value from false to true, a user is able to gain access to the admin dashboard interface. However, despite accessing the admin panel, the user does not have sufficient permissions to view or interact with actual data.
PoC
Intercept the login response and change "isMasterAdmin": false → "isMasterAdmin": true
Impact
The admin dashboard is viewable.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2025-66028? CVE-2025-66028 is a medium-severity incorrect authorization vulnerability in @oneuptime/common (npm), affecting versions < 8.0.5567. It is fixed in 8.0.5567. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- Which versions of @oneuptime/common are affected by CVE-2025-66028? @oneuptime/common (npm) versions < 8.0.5567 is affected.
- Is there a fix for CVE-2025-66028? Yes. CVE-2025-66028 is fixed in 8.0.5567. Upgrade to this version or later.
- Is CVE-2025-66028 exploitable, and should I be worried? Whether CVE-2025-66028 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-66028 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
