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 confidenceA Cross-Site Request Forgery (CSRF) vulnerability in the spam-stopper WordPress plugin (versions <= 3.1.3) allows authenticated administrators to be tricked into submitting malicious requests that inject persistent Cross-Site Scripting (XSS) payloads. The lack of CSRF token validation on plugin forms enables attackers to craft malicious links or pages that, when visited by a logged-in administrator, silently submit forms containing XSS payloads that are stored in the database.

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 spam-stopper plugin versionIn WordPress admin, go to Plugins > Installed Plugins > find spam-stopper and check the version number displayed under the plugin name. Alternatively, inspect the plugin main file header for the 'Version' tag.Affected if The installed version is 3.1.3 or lower.
-
Verify plugin is activeConfirm the spam-stopper plugin is currently activated in the WordPress plugins panel. The vulnerability only affects active plugin installations.Affected if The plugin is installed and active with a vulnerable version.
-
Check for admin session exposureReview which user accounts have Administrator role and determine if they access the WordPress admin panel. The CSRF attack requires a logged-in administrator to visit a malicious link.Affected if There are active administrator accounts who could be targeted.
-
Inspect plugin form submissionsExamine the plugin settings pages (typically under Settings > spam-stopper) where user input is saved to the database. Look for forms that handle keyword filtering, message customization, or other stored data without visible CSRF token fields.Affected if Plugin forms lack CSRF token validation (visible as missing token fields in HTML source).
You are affected if the spam-stopper plugin version is 3.1.3 or lower, the plugin is active, and administrator sessions exist in the environment.

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 dataUpdate to the latest version of spam-stopper if a patched release is available. Until then, disable the plugin or implement additional security measures such as configuring a WAF to filter CSRF attacks.
