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 Denis Kobozev CSV Importer.This issue affects CSV Importer: from n/a through 0.3.8.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in Denis Kobozev CSV Importer plugin (versions through 0.3.8). The plugin lacks proper anti-CSRF mechanisms on state-changing operations, allowing attackers to trick authenticated users into performing unintended actions such as manipulating CSV import configurations or data.

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 plugin installation and versionLocate the Deniskobozev CSV Importer plugin in your WordPress plugins directory (typically wp-content/plugins/csv-importer). Open the main plugin PHP file and locate the version number in the plugin header comment or version constant.Affected if The installed version is 0.3.8 or lower (including any 0.x.x version through 0.3.8).
-
Inspect PHP files for nonce verificationSearch all PHP files in the plugin for WordPress nonce verification functions such as wp_verify_nonce, check_admin_referer, or check_ajax_referer. These functions should be present in any file handling form submissions or state-changing operations.Affected if No nonce verification calls are found in files that handle form submissions, AJAX requests, or other state-changing operations.
-
Examine form implementations for nonce fieldsReview PHP files that generate HTML forms (look for <form> tags and input fields). Check if forms include nonce input fields (typically using wp_nonce_field or similar functions) to protect against CSRF.Affected if Forms that perform state-changing operations lack nonce input fields.
-
Check AJAX handlers for CSRF protectionLocate AJAX action handlers in the plugin (search for add_action calls with wp_ajax_ or wp_ajax_nopriv_ hooks). Verify that these handlers include nonce verification before processing requests.Affected if AJAX handlers that modify data or configuration lack nonce validation logic.
-
Verify cookie SameSite attribute configurationSearch plugin PHP files for setcookie function calls and check if the SameSite attribute is set (for example, SameSite=Strict or SameSite=Lax). Also check if the plugin sets any custom cookies without proper SameSite attributes.Affected if The plugin sets cookies without SameSite attributes or does not properly configure cookies for CSRF protection.
You are affected if the CSV Importer plugin version is 0.3.8 or lower AND state-changing operations (forms, AJAX endpoints) lack anti-CSRF mechanisms such as nonce verification, SameSite cookies, or Origin/Referer header validation.

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 state-changing operations (forms, API endpoints), enable SameSite cookie attributes, and validate Origin/Referer headers to prevent cross-site request forgery attacks.
