CVE-2025-23552

Vulnerability

Analysis

The Texteller plugin for WordPress, up to version 1.3.0, contains a reflected Cross-Site Scripting (XSS) vulnerability. The root cause is the improper neutralization of user-supplied input during web page generation. This flaw allows an attacker to inject malicious scripts into a web page, which will be reflected to the user's browser [1].

Exploitation

Exploitation of this vulnerability requires user interaction. An attacker must trick a privileged user, such as an administrator, into clicking a crafted link or submitting a specially designed form. The attack does not require authentication with the targeted site, but it does rely on a user with elevated privileges performing an action [1].

Impact

Successful exploitation enables an attacker to inject arbitrary HTML and JavaScript into the vulnerable page. This could be used to perform actions such as redirecting users to malicious sites, displaying unwanted advertisements, or stealing sensitive information. The CVSS v3.1 base score is 7.1 (High), indicating a significant security risk [1].

Mitigation

The vendor has not released an official patch; however, a mitigation rule from Patchstack is available to block attacks. As an immediate action, users should update the plugin to the latest version. If an update is not available, contacting a hosting provider or web developer for alternative mitigation steps is recommended [1].
