CVE-2025-23989
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in Alessandro Piconi Internal Link Builder internal-link-builder allows Cross Site Request Forgery.This issue affects Internal Link Builder: from n/a through <= 1.0.
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 confidenceCSRF vulnerability in the Internal Link Builder plugin allows attackers to forge authenticated requests by tricking logged-in administrators into visiting malicious pages. The lack of anti-CSRF tokens on state-changing operations enables unauthorized modification of internal links.

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.
-
Locate the Internal Link Builder plugin filesAccess your site's wp-content/plugins directory and identify the Internal Link Builder plugin folder (often named 'internal-link-builder' or similar)Affected if The plugin folder exists and contains PHP files handling form submissions or AJAX requests
-
Inspect form handlers for nonce verificationOpen the main plugin PHP files and search for 'wp_nonce_field', 'wp_verify_nonce', 'check_admin_referer', or 'check_ajax_referer' functions in files handling state-changing operations (form submissions, settings saves, link modifications)Affected if No nonce verification is found in files that handle POST/DELETE requests modifying link data
-
Check AJAX endpoints for CSRF protectionSearch for 'add_action' hooks registering AJAX actions (wp_ajax_*) and verify each handler calls nonce verification functions before processing requestsAffected if AJAX handlers exist but do not verify nonces before executing state-changing operations
-
Verify Origin/Referer header validationSearch plugin code for '$_SERVER[HTTP_ORIGIN]' or '$_SERVER[HTTP_REFERER]' validation, or check if WordPress's 'check_admin_referer' is used which includes this checkAffected if No origin or referer header validation is performed on POST requests
-
Identify state-changing operations lacking protectionReview code for form actions, database write operations (insert, update, delete on links table), or settings changes that process without nonce validationAffected if Any link creation, modification, deletion, or bulk operations process requests without anti-CSRF token validation
Your environment is affected if the Internal Link Builder plugin is installed and its state-changing operations (link creation, modification, deletion) process requests without verifying anti-CSRF tokens (nonces) or validating Origin/Referer headers.
Generated from the published advisory. Verify against your own configuration.
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 anti-CSRF tokens (synchronizer token pattern) on all POST/PUT/DELETE endpoints and validate Origin/Referer headers to prevent cross-origin forged requests.
