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 · unedited
An authorization vulnerability exists in Innoshop 0.6.0. After logging into the frontend, an attacker can directly access backend application interfaces, leading to further dangerous operations.

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 confidence

Innoshop 0.6.0 contains an authorization flaw where authenticated frontend users can directly access backend application interfaces without proper authorization verification. This broken access control allows privilege escalation by enabling standard users to reach administrative endpoints after logging into the frontend.

MitigationImplement server-side authorization checks on all backend routes to verify that the requesting user has appropriate backend privileges before granting access to administrative functions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Innoshop version
    Locate the version file or bootstrap file in the Innoshop installation directory (commonly version.php, composer.json, or index.php header) and read the declared version number
    Affected if Version is 0.6.0 exactly or falls within the 0.6.x branch
  2. Inspect session role validation on backend routes
    Examine the backend controller files (typically in a /backend or /admin directory) and verify whether each controller action checks the user's role or permission level before executing
    Affected if Backend controllers lack role-based authorization checks and only rely on frontend session existence
  3. Test backend access after frontend authentication
    Log in as a regular frontend user, then attempt to access a known backend endpoint (such as /admin, /backend/users, or /backend/settings) using the same session cookies
    Affected if Regular authenticated frontend users can access backend administrative interfaces without receiving a 403 Forbidden or redirect to an unauthorized page
  4. Review route definitions for access control
    Inspect the route definition files (routes/web.php or similar) to determine whether backend routes are protected by middleware that verifies administrative roles, not just authentication
    Affected if Backend routes only have 'auth' or 'guest' middleware without role-specific guards

You are affected if running Innoshop 0.6.0 and regular frontend users can access backend administrative interfaces without proper role-based authorization.
