CVE-2026-6280
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedExposure of sensitive information due to incompatible policies vulnerability in NOMYSOFT Informatics Education and Consulting Inc. Nomysem allows Accessing Functionality Not Properly Constrained by ACLs. This issue affects Nomysem: through 08072026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNomysem contains a broken access control vulnerability where the application fails to properly constrain functionality by Access Control Lists (ACLs). This allows authenticated users to access sensitive information or functionality they should not have permission to view or manipulate, resulting in unauthorized exposure of data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Nomysem installation and versionLocate the Nomysem application installation directory and check for version information in configuration files, metadata, or the application's about/ status page. Compare the installed version against any official release notes or security advisories for CVE-2026-6280.Affected if The installed version matches or falls within an affected version range that contains this vulnerability.
-
Review Access Control List configurationsExamine the ACL configuration files or database tables that define user roles and permissions. Look for entries that control access to sensitive functions, data endpoints, or administrative features.Affected if ACLs are missing, improperly defined, or fail to restrict access to sensitive functionality for lower-privileged user roles.
-
Test vertical privilege escalationCreate or use a low-privilege authenticated user account and attempt to access higher-privileged functions, administrative panels, or sensitive data endpoints that should be restricted to elevated roles.Affected if A lower-privileged user can successfully access functionality or data that should require higher privileges.
-
Audit endpoint permission enforcementReview application source code or API documentation to identify all endpoints and functions. For each, verify that permission checks are performed before executing the requested operation.Affected if Endpoints or functions lack proper permission validation or allow bypasses of ACL enforcement.
-
Inspect role-based access control implementationExamine how roles are assigned to users and how those roles are validated during request processing. Check if role checks are consistently enforced across all application components.Affected if Role assignments can be manipulated, role checks are inconsistent, or certain components bypass role validation.
The environment is affected if the installed Nomysem version is within the affected range AND ACLs are either missing, misconfigured, or can be bypassed to allow unauthorized access to sensitive functionality.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper role-based access control (RBAC) and ensure all endpoints and functions validate user permissions against ACLs before granting access. Conduct a comprehensive audit to identify all unprotected functionality.
