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
Cross-site request forgery (CSRF) vulnerability in the MRBS module for Drupal allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.

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

Cross-site request forgery (CSRF) vulnerability in the MRBS (Meeting Room Booking System) Drupal module enables remote attackers to perform actions on behalf of authenticated users by tricking them into visiting malicious pages. The specific attack vectors and affected endpoints are not detailed in the available description, but the vulnerability allows authentication hijacking of unspecified victims.

MitigationImplement anti-CSRF tokens (form tokens) on all state-changing operations in the MRBS module, and ensure Drupal's built-in CSRF protection is properly utilized for all AJAX and form submissions. Verify all user actions require proper token validation.

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. Confirm MRBS module installation
    In Drupal admin panel, navigate to Modules (admin/modules) and check if 'Meeting Room Booking System' or 'MRBS' is listed and enabled. Alternatively, check the Drupal modules directory for the mrbs folder (typically sites/all/modules/mrbs or modules/mrbs).
    Affected if MRBS module is present and enabled in the Drupal installation
  2. Identify MRBS module file location
    Locate the MRBS module directory in the Drupal installation - commonly at sites/all/modules/mrbs/ or profiles/*/modules/mrbs/. Identify PHP files handling form submissions (typically files with 'form' or 'request' in the name).
    Affected if MRBS module files exist in the Drupal modules directory
  3. Check form handling code for token validation
    Examine the MRBS PHP files that process state-changing operations (POST requests). Search for Drupal form API calls and verify whether form_token, drupal_get_token, or Drupal\Core\Form\FormStateInterface methods are used for CSRF protection. Look for 'form_build_id' and '#token' elements in form definitions.
    Affected if State-changing operations lack form token validation (no form_token, drupal_get_token, or token validation calls found)
  4. Inspect AJAX endpoints for CSRF protection
    Review AJAX callback functions in MRBS module for proper token validation. Check if AJAX requests validate the user session or use Drupal's AJAX framework which includes token protection. Look for 'ajax_callback' functions and verify they check user authentication.
    Affected if AJAX endpoints accept requests without validating CSRF tokens or user session

A user is affected if the MRBS Drupal module is installed and the code handling forms and state-changing operations does not implement Drupal's built-in form token validation mechanisms.
