CVE-2025-23469

Vulnerability

Overview

CVE-2025-23469 is a reflected Cross-Site Scripting (XSS) vulnerability in the Sleekplan plugin for WordPress, affecting versions from n/a through 0.2.0. The root cause is improper neutralization of user-supplied input during web page generation, enabling an attacker to inject arbitrary HTML or JavaScript into the application's response [1].

Exploitation

Conditions

Exploitation requires a privileged user to perform an action such as clicking a crafted link, visiting a specially prepared page, or submitting a malicious form. The attacker does not need prior authentication to lure the victim, but the attack depends on user interaction to trigger payload execution [1].

Impact

Successful exploitation allows an attacker to inject malicious scripts, which may be used to execute actions like redirecting visitors to harmful sites, displaying unauthorized advertisements, or exfiltrating sensitive information from the WordPress context [1].

Mitigation

The vendor has not yet released an official patch, but Patchstack has published a mitigation rule to block exploitation attempts until the plugin is updated [1]. Administrators are advised to update the plugin immediately when a fix becomes available or to apply a temporary workaround via a web application firewall.
