CVE-2025-46440

Vulnerability

Overview CVE-2025-46440 is a reflected cross-site scripting (XSS) vulnerability in the WordPress kStats Reloaded plugin, affecting versions up to and including 0.7.4. The issue stems from improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary HTML and JavaScript into a response [1].

Exploitation

Details Exploitation requires user interaction: a privileged user (e.g., an administrator) must click a malicious link, visit a crafted page, or submit a specially crafted form. The attacker does not need authentication but relies on tricking a legitimate user into performing an action that triggers the reflected XSS [1].

Impact

Successful exploitation enables the attacker to inject malicious scripts, such as redirects, advertisements, or other HTML payloads. These scripts execute in the context of the victim's browser when they visit the affected site, potentially leading to session hijacking, defacement, or theft of sensitive data [1].

Mitigation

As an immediate step, update the kStats Reloaded plugin to a patched version if available. If no official patch exists, apply a web application firewall (WAF) rule or use Patchstack's mitigation rule to block attacks until a fix can be deployed [1].
