HIGH 7.1

DescriptionCVE.org

The 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.

AnalysisAI

Reflected cross-site scripting in the EventPress WordPress theme (all versions before 22.2) lets unauthenticated attackers inject arbitrary JavaScript by abusing the unsanitized 'id' parameter in the eventpress_customizer_notify_dismiss_action AJAX handler, which echoes the value back into the response without escaping. An attacker who lures a logged-in user (typically an administrator working in the Customizer/admin context) to a crafted link executes script in that user's session, enabling actions such as session/cookie theft or admin-context operations. EPSS exploitation probability is very low (0.05%, 17th percentile), there is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Technical ContextAI

The flaw lives in a WordPress theme AJAX endpoint registered through WordPress's admin-ajax.php mechanism (the eventpress_customizer_notify_dismiss_action handler, tied to the theme Customizer's notification-dismiss feature). User-supplied input via the 'id' request parameter is reflected directly into the HTTP response body without sanitization or output escaping, the textbook root cause of CWE-79 (Improper Neutralization of Input During Web Page Generation). Because WordPress AJAX actions prefixed with wp_ajax_nopriv_ are reachable without authentication, the handler is exposed to anonymous requests, and the absence of an escaping function (e.g., esc_html/esc_attr) on output is what turns reflected input into executable markup in the victim's browser.

RemediationAI

Vendor-released patch: 22.2 - update the EventPress theme to version 22.2 or later, which adds the missing sanitization/escaping on the reflected 'id' value. Consult the WPScan advisory at https://wpscan.com/vulnerability/77192aeb-8e4b-4057-b5d7-2b95da634edd/ for confirmation of the fixed release. If immediate upgrade is not possible, deploy compensating controls: place a WAF rule to block or strip script-like payloads and angle brackets in the 'id' parameter on requests to admin-ajax.php for the eventpress_customizer_notify_dismiss_action action (trade-off: may break the legitimate dismiss feature and can be bypassed by encoding tricks), and restrict access to /wp-admin/ and admin-ajax.php by IP allowlisting where feasible (trade-off: hampers remote administrators). Reflected XSS still requires tricking an authenticated user, so reinforce admin awareness about clicking untrusted links and consider a strict Content-Security-Policy that disallows inline script (trade-off: may interfere with plugins/themes that rely on inline JavaScript).
