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
Authorization bypass through User-Controlled key vulnerability in Idvlabs Software and Consulting Services Inc. Ontime allows Exploitation of Trusted Identifiers. This issue affects Ontime: through 04052026.

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

This is an Insecure Direct Object Reference (IDOR) vulnerability where the application trusts user-controlled identifiers (such as object IDs in requests) without proper authorization validation. Attackers can manipulate these trusted identifiers to access resources belonging to other users or elevate privileges beyond what their account should permit.

MitigationImplement proper authorization checks on every API endpoint and UI action that references object identifiers. Verify that the authenticated user has explicit permission to access the requested resource before returning any 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 checks

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

  1. Map object identifier entry points
    Review your API endpoints, URLs, and request parameters for patterns where user-supplied IDs (such as /users/123, ?id=123, or {"resource_id": 123} in request body) are used to reference data objects
    Affected if your application accepts object identifiers from users without requiring authorization validation on each request
  2. Verify authorization on identifier-based access
    Examine the code or configuration for each endpoint that uses object IDs to confirm that an authorization check verifies the authenticated user owns or has permission to access the specific resource before returning data
    Affected if any endpoint that uses object identifiers lacks explicit authorization logic that validates user permissions for that specific resource
  3. Test for cross-user object access
    Using two different test accounts, attempt to access or modify a resource belonging to account A by using account A's object identifiers while authenticated as account B
    Affected if manipulating object identifiers from one user allows access to another user's resources
  4. Check for privilege escalation paths
    Identify endpoints that modify resource ownership or permissions and verify whether user-controlled identifiers can elevate privileges beyond the authenticated user's role
    Affected if object identifiers can be manipulated to gain access to administrative functions or elevated privileges
  5. Review indirect reference maps
    If your application uses indirect or mapped references (such as random tokens instead of sequential IDs), verify that these mappings cannot be enumerated or predicted to access other objects
    Affected if object references are predictable or enumerable rather than randomly mapped

A user is affected if their application uses object identifiers from user requests without performing explicit authorization validation for each access attempt.
