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

A Cross-Site Request Forgery (CSRF) vulnerability exists in Build App Online versions up to 1.0.23. Attackers can trick authenticated users into unknowingly submitting malicious requests to the application, potentially performing unauthorized actions on behalf of the victim.

MitigationImplement anti-CSRF tokens on state-changing operations and configure SameSite cookie attributes. Alternatively, validate Origin/Referer headers for incoming requests.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Build App Online installation
    Locate the Build App Online installation and determine the installed version number. Consult the application's documentation, admin panel, or version information file.
    Affected if The installed version is 1.0.22 or lower.
  2. Verify web interface is exposed
    Confirm that the Build App Online web interface is accessible to users or attackers over the network.
    Affected if The application web interface is accessible and accepts authenticated user sessions.
  3. Review state-changing operations
    Identify forms or API endpoints that perform state-changing actions (e.g., user management, configuration changes, data submission). Examine the request handlers for these operations.
    Affected if State-changing operations exist that process requests without validating CSRF tokens.
  4. Inspect cookie configuration
    Examine the application's session cookies and their attributes. Check if SameSite attributes are set to 'Strict' or 'Lax', or if the application validates Origin/Referer headers.
    Affected if Session cookies lack SameSite attributes and the application does not validate Origin/Referer headers on state-changing requests.
  5. Audit authentication mechanism
    Determine if the application uses cookie-based authentication for authenticated users.
    Affected if The application relies on cookie-based authentication for user sessions.

The environment is affected if Build App Online version 1.0.22 or lower is running with its web interface accessible and state-changing operations lack CSRF protection (missing tokens and no SameSite cookie/Origin header validation).

Upgrade available Upgrade to a release after 1.0.22
Interim mitigation

Implement anti-CSRF tokens on state-changing operations and configure SameSite cookie attributes. Alternatively, validate Origin/Referer headers for incoming requests.

Recommended fix Moderate confidence
