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.
-
Verify LearnPress plugin is installedCheck your WordPress site's wp-content/plugins/ directory for the learnpress folder, or log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins to confirm LearnPress is listed and active.Affected if LearnPress plugin is installed and active on the WordPress site.
-
Identify installed LearnPress versionIn WordPress admin, find LearnPress in the plugins list and note the version number displayed. Alternatively, open /wp-content/plugins/learnpress/readme.txt and check the top of the file for the current version.Affected if The installed version is unknown or falls within any vulnerable version range.
-
Check for user-facing forms or search functionalityVisit your LearnPress pages (course listings, enrollment forms, profile pages) and inspect any input fields or URL parameters that accept user data. Look for query parameters in URLs that might reflect back submitted values.Affected if The plugin has any user input fields or URL parameters that could be manipulated.
-
Inspect for unsanitized output in reflected parametersSubmit a test string with special characters (e.g., <script>alert(1)</script>) in any LearnPress input fields or URL parameters, then check the page source or browser developer tools to see if the input is rendered without HTML encoding.Affected if User-supplied input is reflected back in the page output without proper escaping (the test string appears as raw HTML/JavaScript rather than being encoded).
A user is affected if LearnPress is installed, any version is in use, and the plugin reflects user input in web pages without HTML encoding.
