CVE-2021-25097
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 · uneditedThe LabTools WordPress plugin through 1.0 does not have proper authorisation and CSRF check in place when deleting publications, allowing any authenticated users, such as subscriber to delete arbitrary publication
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 confidenceThe LabTools WordPress plugin through version 1.0 lacks proper authorization checks and CSRF protection when deleting publications. The deletion endpoint does not verify if the authenticated user has sufficient privileges to delete the target publication, allowing any logged-in user (including subscribers with minimal permissions) to delete arbitrary publications via IDOR.

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.
-
Identify LabTools plugin installation and versionIn WordPress admin, go to Plugins > Installed Plugins and look for 'LabTools' or 'Creativityjuice Labtools'. Check the version number displayed under the plugin name. Alternatively, examine the plugin header in wp-content/plugins/labtools/labtools.php for the 'Version' tag.Affected if The plugin is installed with version 1.0 or lower
-
Check if deletion functionality existsLocate the PHP file handling publication deletion within the plugin directory (commonly labtools.php or a dedicated class). Search for functions handling 'delete' or 'remove' operations on publications/posts.Affected if A deletion function for publications exists in the plugin code
-
Verify user role requirements for deletionExamine the deletion function code to determine what capability check, if any, is performed before allowing deletion. Look for current_user_can() calls or privilege verification logic immediately before the delete operation.Affected if No current_user_can('delete_post', $post_id) or equivalent capability check exists before the deletion executes
-
Test lower-privileged user accessUsing a test subscriber-level account, attempt to access the deletion endpoint (typically a POST/GET request to an admin URL or AJAX handler with a publication ID parameter). Observe if the request succeeds and the publication is deleted without permission error.Affected if A subscriber-level user can successfully delete publications they did not create
You are affected if LabTools plugin version 1.0 or lower is installed AND the deletion function lacks proper capability checks, allowing any logged-in user to delete arbitrary publications.

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.
From vendor dataImplement WordPress capability checks (e.g., current_user_can('delete_post', $post_id)) before allowing deletion, and add nonces/CSRF tokens to validate request origin and intent.
