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

Missing Authorization vulnerability in merkulove Sliper for Elementor plugin allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthenticated or under-privileged users to access functionality they should not have permission to use.

MitigationImplement proper capability checks and authorization validation for all sensitive functions and AJAX endpoints within the plugin to enforce correct access control security levels.

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. Verify plugin installation
    Navigate to WordPress dashboard > Plugins and confirm 'Sliper for Elementor' by merkulove is installed and activated
    Affected if plugin is installed and active
  2. Identify installed version
    In Plugins list, click on the plugin to view version details, or check the plugin header in /wp-content/plugins/sliper-for-elementor/ folder
    Affected if version is within the affected range (if any ranges are known)
  3. Inspect AJAX endpoint registration
    Search plugin PHP files for 'add_action' calls registering AJAX actions (wp_ajax_*) and check if they include capability checks via 'check_ajax_referer' or current_user_can before processing
    Affected if AJAX endpoints lack capability verification and are accessible to low-privileged or unauthenticated users
  4. Review sensitive function access controls
    Examine plugin PHP files for functions handling sensitive operations (settings changes, data access, content modification) and verify they include current_user_can() or similar authorization checks
    Affected if sensitive functions execute without verifying user capabilities

User is affected if the Sliper for Elementor plugin is installed and its AJAX endpoints or sensitive functions lack proper capability checks, allowing unauthorized access.
