CVE-2025-53225

Vulnerability

Overview

The e-Boekhouden.nl plugin for WordPress (versions n/a through 1.9.3) contains a reflected Cross-Site Scripting (XSS) vulnerability. The plugin fails to properly neutralize input during web page generation, enabling injection of arbitrary HTML and JavaScript into the response [1]. This stems from insufficient sanitization of user-supplied data before it is included in output pages.

Exploitation

Method

This is a reflected XSS attack, meaning the attacker must trick a privileged user (e.g., an admin) into interacting with a crafted link, visiting a malicious page, or submitting a specially crafted form [1]. An unauthenticated attacker can craft the payload, but successful execution depends on a user with the necessary privileges performing the action. The vulnerability requires no special network position beyond standard web access.

Impact

If successfully exploited, an attacker can inject malicious scripts into the affected WordPress site. This can lead to actions such as redirecting visitors to attacker-controlled sites, injecting unwanted advertisements, or deploying other HTML-based payloads [1]. The injected script runs in the context of the user's session, potentially allowing further actions like stealing cookies or session tokens.

Mitigation

The vendor has not released a patched version at this time. However, a mitigation rule is available from Patchstack to block attacks until an official patch is applied [1]. Users are urged to update the plugin immediately when a security update becomes available, or contact their hosting provider if they cannot update directly.
