NVD · uneditedUnauthenticated Insecure Direct Object References (IDOR) in Blocksy Companion Pro <= 2.1.46 versions.
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 · high confidenceUnauthenticated IDOR vulnerability in Blocksy Companion Pro <= 2.1.46 allows unauthenticated attackers to access or modify objects (such as posts, user data, or settings) by manipulating direct object references without proper authorization checks.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Blocksy Companion Pro is installedCheck the WordPress plugins list or inspect the plugin files in wp-content/plugins/blocksy-companion-pro to verify the plugin is presentAffected if Blocksy Companion Pro is installed and active
-
Identify the installed versionView the plugin header in main plugin file (typically blocksy-companion-pro.php) or check the WordPress plugins admin page to find the exact version numberAffected if Version is 2.1.46 or lower (any version <= 2.1.46)
-
Verify the plugin is exposed to unauthenticated requestsTest access to any public-facing endpoints or AJAX actions used by the plugin (check wp-admin/admin-ajax.php and REST API routes registered by the plugin) without providing authentication credentialsAffected if The plugin accepts unauthenticated requests to endpoints that handle object references (posts, user data, or settings)
-
Check for direct object reference usageInspect plugin code or monitor HTTP requests to identify if the plugin processes object IDs, post IDs, user IDs, or similar identifiers through URL parameters (such as id, post_id, user_id, object_id) without additional authorization validationAffected if The plugin processes direct object identifiers from unauthenticated requests without validating user permissions
User is affected if Blocksy Companion Pro version 2.1.46 or lower is installed and the plugin exposes any unauthenticated endpoints that handle direct object references without authorization checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate Blocksy Companion Pro to version 2.1.47 or later. If patching is not immediately possible, implement server-side authorization checks on all object references and audit access controls.
Latest version of Blocksy Companion Pro (version > 2.1.46)
- Upgrade Blocksy Companion Pro to the latest available version from the vendor or WordPress repository
- Verify the installation of the updated version after upgrading
- Test the site's functionality after the upgrade to ensure compatibility
