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 plugin installation and active statusNavigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'Eli Anti-Malware Security and Brute-Force Firewall' in the list and verify it is activated.Affected if The plugin is installed and active in WordPress
-
Identify installed plugin versionIn the plugins list, click on the plugin name or view the plugin files. Open the main plugin file (usually named like eli-anti-malware.php or similar) and locate the version declaration in the plugin header comment.Affected if Plugin version is unknown or cannot be determined from the plugin files
-
Locate user input handling codeExamine PHP files in the plugin directory for code that handles $_GET, $_POST, or $_REQUEST superglobals. Search for parameters that get echoed or printed back to the user without obvious sanitization functions.Affected if The plugin contains code that reflects user-supplied input directly into HTML output
-
Inspect output encoding in reflected input pathsReview the identified user input handlers. Check if functions like htmlspecialchars(), esc_html(), esc_attr(), or similar encoding functions are used before outputting user data to HTML pages.Affected if User input is reflected in HTML output without proper output encoding functions
-
Test for reflected XSS via browserIdentify any frontend-facing plugin pages or admin pages that accept user input. Submit a harmless test payload like <script>alert('test')</script> in available input fields and observe if it executes or appears unencoded in the response.Affected if The test payload executes as JavaScript or appears unencoded in the page source
You are affected if the Eli Anti-Malware Security plugin is active and contains code paths where user input is reflected in HTML pages without using output encoding functions like htmlspecialchars(), esc_html(), or esc_attr().

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 proper input validation and output encoding/escaping for all user-supplied data before rendering in HTML pages. Update the plugin to version 4.23.90 or later if a patch is available.
