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 code injection vulnerability exists in the Widget Options plugin (versions up to 4.1.3) that allows attackers to inject malicious code through the plugin's widget-options functionality. The vulnerability stems from improper control of code generation, likely due to insufficient input validation or unsafe use of user-supplied data in code execution contexts.

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 Widget Options plugin is installedLocate the plugin directory in your WordPress installation (typically wp-content/plugins/widget-options) and verify the plugin files exist. In WordPress admin, check Plugins > Installed Plugins for 'Widget Options'.Affected if The plugin is present on the system.
-
Determine the installed versionRead the main plugin file (usually widget-options.php) and locate the version defined in the plugin header comment (e.g., 'Version: x.x.x'). Compare this version to the affected range of 4.1.3 and below.Affected if The installed version is 4.1.3 or any earlier version.
-
Verify widget-options functionality is in useCheck your WordPress widgets configuration (Appearance > Widgets) to see if any widgets have custom 'Widget Options' applied. Also review active theme functions.php for calls to widget_options related functions.Affected if The widget-options feature is actively configured or the plugin is loaded on the site.
-
Review access logs for injection attemptsInspect web server access logs (Apache/nginx) for POST or GET requests to endpoints containing 'widget-options', 'option_tree', or suspicious patterns with code execution keywords (eval, base64_decode, system, exec).Affected if Malicious requests targeting the vulnerable parameter are found in logs.
-
Check for unauthorized code modificationsCompare the plugin files (especially widget-options.php and any files handling the options/settings) against a clean installation from the WordPress repository. Look for base64_decode calls, eval statements, or file creation functions using user input.Affected if Unexpected code execution functions or suspicious modifications exist in plugin files.
You are affected if the Widget Options plugin is installed with version 4.1.3 or lower and the widget-options feature is active or exposed via web 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 dataUpdate Widget Options plugin to the latest version immediately; if no patch is available, disable the plugin until a fix is released. Implement Web Application Firewall rules to block injection attempts targeting the affected endpoint.
