CVE-2026-6268
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe EventPress WordPress theme before 22.2 does not sanitize or escape the 'id' parameter in the eventpress_customizer_notify_dismiss_action AJAX handler before outputting it back in the response, allowing unauthenticated attackers to perform Reflected Cross-Site Scripting attacks against logged-in users.
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 · high confidenceReflected Cross-Site Scripting (XSS) vulnerability in the EventPress WordPress theme (versions before 22.2). The eventpress_customizer_notify_dismiss_action AJAX handler fails to sanitize or escape the 'id' parameter before reflecting it in the response, allowing unauthenticated attackers to inject malicious JavaScript that executes in logged-in users' browsers.

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 if EventPress theme is installedCheck the theme directory for EventPress: look in wp-content/themes/ for an eventpress folder, or use WP CLI: wp theme list --status=activeAffected if EventPress theme is active and present in the WordPress installation
-
Determine installed EventPress versionCheck the style.css file in the theme folder for the Version header, or use WP CLI: wp theme get eventpressAffected if Version is below 22.2 (e.g., 22.1, 22.0, older versions)
-
Verify AJAX handler existsCheck for the file containing eventpress_customizer_notify_dismiss_action - typically in functions.php or a related PHP file within the themeAffected if The AJAX handler function exists and is registered with wp_ajax_nopriv_eventpress_customizer_notify_dismiss_action
-
Test if id parameter reflects without sanitizationMake a direct AJAX request to admin-ajax.php with action=eventpress_customizer_notify_dismiss_action and an id parameter containing a test string like <script>alert(1)</script>, then inspect if the response reflects the raw id valueAffected if The response returns the id parameter value unescaped, allowing script injection
User is affected if EventPress theme version is below 22.2 AND the vulnerable AJAX handler is accessible and reflects the id parameter without HTML escaping.

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 · scopedUpdate EventPress theme to version 22.2 or later which includes proper sanitization and escaping of the 'id' parameter in the AJAX handler.
EventPress theme version 22.2 or later
- Log in to the WordPress admin dashboard
- Navigate to Appearance > Themes

- If an update is available, click to update to version 22.2 or later
- Alternatively, upload and install EventPress version 22.2 or latest from a trusted source
- Clear any caching plugins or server-side caches after updating
- Verify the theme version reflects 22.2 or later in the themes list
