CVE-2025-23563

Vulnerability

Overview CVE-2025-23563 is a reflected Cross-Site Scripting (XSS) vulnerability in the WordPress plugin 'Explore pages' (versions up to and including 1.01). The issue stems from improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary HTML or JavaScript into the response [1].

Exploitation

Requirements Exploitation does not require authentication from the attacker, but it does require user interaction — a victim (such as an administrator or site visitor) must click a crafted link, visit a maliciously prepared page, or submit a specially designed form. The vulnerability is classified as reflected XSS, meaning the injected payload is part of the current request and is not stored on the server [1].

Impact

A successful attack could allow a malicious actor to inject arbitrary scripts into the rendered page, leading to actions such as redirecting users to malicious sites, displaying unwanted advertisements, or performing other HTML-based attacks when visitors access the compromised page. This can compromise the integrity of the site and affect its users. The CVSS v3 score is 7.1 (High) [1].

Mitigation

As of the publication date (2025-03-03), an official patch may not yet be available. However, the Patchstack advisory recommends applying their mitigation rule to block attacks until a verified fix can be deployed. Users should update the plugin to a patched version as soon as it becomes available. If unable to update immediately, seeking assistance from a hosting provider or web developer is advised [1].
