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

The vulnerability is an authorization bypass through user-controlled keys in Idvlabs Ontime application. Attackers can manipulate trusted identifiers (such as session tokens, user IDs, or other security-critical parameters) that the application trusts without proper validation, allowing unauthorized access to resources or actions beyond the user's intended privileges.

MitigationImplement proper validation and authorization checks for all user-supplied identifiers, ensuring that trusted identifiers are not directly used without verification. Apply the principle of least privilege and validate user permissions before granting access to any protected resource.

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 if Idvlabs Ontime is installed
    Search for Idvlabs Ontime application files, processes, or services running on the system. Common locations include /opt/, /var/www/, or check running services for 'ontime' or 'idvlabs' processes.
    Affected if The application is present and running on the system.
  2. Determine the installed version
    Locate the application version information - check for version files, About dialogs, or run: ontime --version or ontime -v. Compare against any available version history for Idvlabs Ontime.
    Affected if The installed version matches or precedes the vulnerable version range for CVE-2026-5730.
  3. Examine session token handling configuration
    Review application configuration files for session management settings. Look for parameters controlling token validation, session timeout, or token creation logic.
    Affected if Session tokens or trusted identifiers are processed without cryptographic validation or signature verification.
  4. Inspect authorization logic for user-controlled parameters
    Review application logs or debug output when accessing different resources. Check if user IDs, session IDs, or other security-critical values can be modified in requests without proper authorization checks.
    Affected if The application accepts and trusts user-supplied identifiers (session tokens, user IDs) without validating them against stored session or authorization data.
  5. Test for parameter manipulation
    Send authenticated requests while modifying session tokens, user IDs, or other identifier parameters in the request. Observe if the application grants access based on manipulated values.
    Affected if Modifying user-controlled keys (session tokens, user IDs) in requests allows access to resources or actions outside the user's legitimate privileges.

A user is affected if Idvlabs Ontime is installed and the application trusts user-supplied identifiers (session tokens, user IDs, or similar parameters) without proper validation, allowing unauthorized access through manipulated identifiers.
