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
Missing Authorization vulnerability in bPlugins B Slider b-slider allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects B Slider: from n/a through <= 1.1.30.

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 bPlugins B Slider WordPress plugin (versions <= 1.1.30) contains a missing authorization vulnerability where the plugin fails to properly validate user capabilities before allowing access to certain functionality. This allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized users to access or manipulate slider configurations that should require higher privileges.

MitigationImplement proper capability checks and authorization validation in all plugin functions that handle sensitive operations or access slider data, ensuring users have appropriate WordPress capabilities before granting access.

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. Check if bPlugins B Slider plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'B Slider' by bPlugins, or check the plugin directory (typically /wp-content/plugins/b-slider/) for the existence of the plugin files
    Affected if The plugin is not found in the WordPress installation
  2. Determine the installed plugin version
    In WordPress admin Plugins page, find 'B Slider' and view the version number under the plugin name, or open the main plugin file (usually b-slider.php) and locate the 'Version' header comment
    Affected if Version is 1.1.30 or lower, or version cannot be determined (plugin may be corrupted or heavily modified)
  3. Verify plugin is actively processing slider data
    Check if the plugin handles slider configurations via WordPress AJAX endpoints (wp-admin/admin-ajax.php) or REST API routes that the plugin registers; examine the plugin files for functions that load, save, or display slider data
    Affected if The plugin is active and contains code that handles slider configurations without visible capability checks (e.g., missing current_user_can() calls before sensitive operations)
  4. Identify exposed functionality without authorization checks
    Review plugin PHP files for AJAX action handlers, admin_menu callbacks, or template shortcodes that access or modify slider data; search for patterns like 'add_action' and 'wp_ajax' without preceding current_user_can() validation
    Affected if Any function handling slider configurations lacks proper capability verification before executing

If the bPlugins B Slider plugin is installed with version 1.1.30 or lower and contains functionality that accesses or modifies slider data without verifying user capabilities, the environment is affected by this missing authorization vulnerability.

Mitigation

Implement proper capability checks and authorization validation in all plugin functions that handle sensitive operations or access slider data, ensuring users have appropriate WordPress capabilities before granting access.

Recommended fix Moderate confidence

Update to the latest available version of bSlider (b-slider) plugin (version 1.1.31 or higher)

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate the bSlider (b-slider) plugin
