CVE-2026-6571
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 · uneditedA weakness has been identified in kodcloud KodExplorer up to 4.52. Affected by this vulnerability is the function roleGroupAction of the file /app/controller/systemRole.class.php. Executing a manipulation of the argument group_role can lead to authorization bypass. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. 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 confidenceAn authorization bypass vulnerability exists in KodExplorer up to v4.52 in the roleGroupAction function within /app/controller/systemRole.class.php. By manipulating the group_role parameter, an attacker can bypass authorization checks and potentially gain unauthorized access to role management functionality. The exploit is publicly available, increasing attack risk.

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.
-
Locate KodExplorer installation and versionSearch for KodExplorer on the web server; check for index.php or common installation directories. Review the version file (often in a config file, changelog, or version info in the source).Affected if KodExplorer version 4.52 or earlier is installed
-
Verify vulnerable file existsConfirm the presence of /app/controller/systemRole.class.php in the KodExplorer installation directory.Affected if The file /app/controller/systemRole.class.php exists in the web root
-
Identify if role management is accessibleCheck if the roleGroupAction function is reachable via the web application routing, typically through the role management interface or API endpoint.Affected if Role management functionality is enabled and accessible to the user context being tested
-
Inspect group_role parameter handlingReview HTTP requests to the role management endpoint; examine whether the group_role parameter can be manipulated in requests to the roleGroupAction function.Affected if The application accepts and processes the group_role parameter without proper authorization validation
-
Confirm authorization bypass conditionTest whether a user with limited privileges can modify the group_role parameter to access or modify roles outside their authorized scope.Affected if A user can bypass authorization by manipulating the group_role parameter to access role management functions they should not have access to
A system is affected if KodExplorer version 4.52 or earlier is installed and the roleGroupAction function in systemRole.class.php is accessible, allowing manipulation of the group_role parameter to bypass authorization checks.

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 dataSince the vendor did not respond to disclosure, implement compensating controls such as web application firewall rules to block manipulation of the group_role parameter, or manually audit and patch the roleGroupAction function to enforce proper authorization validation before role operations.
