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 the AntiSpam for Contact Form 7 WordPress plugin (cf7-antispam) allows attackers to induce authenticated users to perform unintended actions, such as submitting spam or manipulating form configurations. The vulnerability exists in versions <= 0.6.3 due to missing or improper anti-CSRF token validation on state-changing operations.

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 cf7-antispam plugin installationCheck if the plugin directory exists at wp-content/plugins/cf7-antispam/ or search for the plugin files in your WordPress installationAffected if The plugin directory exists on the server
-
Determine the installed versionOpen the main plugin file (cf7-antispam.php) and locate the version number in the plugin header comment, or check readme.txt for the 'Stable tag' entryAffected if The version is 0.6.3 or lower (any version <= 0.6.3)
-
Inspect form handling code for nonce validationExamine the main plugin PHP file and look for form submission handlers (functions processing POST requests). Search for presence of wp_verify_nonce(), check_admin_referer(), or wp_nonce_field() calls in functions that handle state-changing operations like saving settings or submitting spamAffected if Form handlers that process state-changing requests lack nonce verification calls (wp_verify_nonce or check_admin_referer not found in those functions)
-
Check admin settings pages for nonce protectionReview any admin menu callback functions that modify plugin configuration. Verify that settings forms include wp_nonce_field() in their output and that the handler functions call wp_verify_nonce() before processingAffected if Admin action handlers missing nonce verification before processing settings changes
You are affected if the cf7-antispam plugin is installed at version 0.6.3 or lower and its form handlers or admin action handlers lack WordPress nonce verification (wp_verify_nonce or check_admin_referer) before processing state-changing requests.

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 nonces on all form outputs within the plugin and verify these nonces on form submission handlers to prevent CSRF attacks. Users should update to a patched version when available or ensure admin actions require proper nonce verification.
