CVE-2025-46526

Vulnerability

Description

The My Custom Widgets plugin for WordPress, versions up to 2.0.5, contains a reflected Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user input during web page generation. This allows an attacker to inject arbitrary HTML and JavaScript into the vulnerable page [1].

Exploitation

Exploitation requires a privileged user (e.g., an administrator) to interact with a crafted link, such as clicking a malicious URL or visiting a specially prepared page. No authentication is needed to trigger the vulnerability, but the victim must be logged into the WordPress site with sufficient privileges for meaningful impact. The attack can be delivered via email, social media, or other channels [1].

Impact

Successful exploitation enables the attacker to execute malicious scripts in the context of the victim's browser. This can lead to session hijacking, defacement, redirection to malicious sites, or theft of sensitive information. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns [1].

Mitigation

The vulnerability is fixed in a later version of the plugin. Users are strongly advised to update to the latest version immediately. If an update is not available, Patchstack offers a mitigation rule to block attacks until an official patch can be applied [1].
