CVE-2026-5247 — Cross-Site Scripting (XSS)

title: WordPress PublishPress Future Stored XSS via wrapper attribute — CVE-2026-5247
id: scw-2026-05-05-ai-1
status: experimental
level: high
description: |
  This rule detects attempts to exploit CVE-2026-5247 in the PublishPress Future WordPress plugin. It specifically looks for requests to 'admin-ajax.php' with the 'future_action' action, containing a 'wrapper=' parameter that includes an event handler attribute (indicated by ' on'). This pattern is indicative of an attacker attempting to inject arbitrary web scripts into pages by exploiting the insufficient sanitization of the 'wrapper' attribute in the [futureaction] shortcode.
