CVE-2026-25442

Vulnerability

Overview The Kentha WordPress theme from QantumThemes contains a reflected cross-site scripting (XSS) vulnerability due to improper neutralization of user input during web page generation. This issue affects all versions up to and including 4.7.2 [1]. The vulnerability is classified as 'Reflected XSS,' where the attacker's payload is included in a request and reflected back in the response without proper sanitization.

Exploitation

Method Exploitation requires user interaction specifically, a privileged user action, such as clicking a crafted link or visiting a specially prepared page. The attacker must convince such a user to perform that action. This property makes it suitable for mass-exploit campaigns, where attackers target thousands of sites regardless of their popularity or traffic [1].

Impact

If successfully exploited, an attacker can inject arbitrary HTML and JavaScript into the affected page. This could lead to redirecting visitors to malicious sites, displaying unauthorized advertisements, or stealing sensitive information. The CVSS v3 score of 7.1 reflects the moderate to high severity of this vulnerability [1].

Mitigation

Status Users are strongly advised to update the theme immediately. For those unable to apply the patch, Patchstack has released a mitigation rule that blocks attacks until an official fix is deployed. Additionally, consulting with a hosting provider or web developer is recommended if immediate action is not possible [1].
