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 Taras Dashkevych error-notification plugin allows remote attackers to trick authenticated users into performing unintended actions by inducing them to send malicious requests. The plugin lacks proper 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.
-
Confirm the plugin is installedIn the WordPress admin dashboard, navigate to Plugins > Installed Plugins and look for 'error-notification' by Taras Dashkevych. Alternatively, check the /wp-content/plugins/ directory for an error-notification folder.Affected if The plugin is installed and active in the WordPress environment
-
Identify the installed plugin versionIn the Plugins list in WordPress admin, click on the plugin name to view details, or open the main plugin PHP file and look for the 'Version' header in the plugin comment block.Affected if The installed version is unknown or falls within a vulnerable range (the vulnerability exists in versions lacking anti-CSRF token validation)
-
Locate state-changing functionalityExamine the plugin files for form handlers and action endpoints that modify data, typically found in files with names like admin.php, ajax-handler.php, or functions that process POST/GET requests for settings, notifications, or user actions.Affected if The plugin contains forms or URLs that perform state-changing operations such as saving settings, creating/updating/deleting records, or triggering notifications
-
Verify absence of nonce verificationOpen the identified state-changing PHP files and search for calls to wp_verify_nonce, check_admin_referer, or nonces in form fields (wp_nonce_field, wp_nonce_url). Check if these verifications are properly implemented before any database writes or configuration changes.Affected if State-changing operations lack proper nonce verification or use nonces inconsistently/incorrectly
-
Check form implementation for CSRF tokensIf the plugin provides frontend or admin forms, view the page source or inspect the HTML to verify that each form includes a hidden nonce field (typically named _wpnonce or similar) and that the form action URLs do not bypass token validation.Affected if Forms submitting to state-changing endpoints do not include CSRF tokens or the tokens are not validated server-side
A user is affected if the error-notification plugin is installed and its state-changing operations lack proper anti-CSRF token validation on the server side.

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.
dbcve · scopedImplement anti-CSRF tokens (synchronizer token pattern) on all forms and state-changing requests, and validate Origin/Referer headers to prevent cross-site request forgery attacks.
