CVE-2025-57996

Vulnerability

Overview CVE-2025-57996 is a stored cross-site scripting (XSS) vulnerability in the Buckets WordPress plugin, affecting versions from n/a through 0.3.9. The root cause is improper neutralization of user-supplied input during web page generation, which allows an attacker to inject arbitrary HTML and JavaScript code that is stored on the server and later executed in the browsers of visitors [1].

Exploitation

Prerequisites Exploitation requires a privileged user (e.g., an administrator) to perform an action such as clicking a malicious link or submitting a crafted form. This means the attacker must first convince a privileged user to trigger the payload, after which the injected script becomes persistent and executes for all subsequent visitors [1].

Impact

Successful exploitation enables an attacker to inject malicious scripts, including redirects, advertisements, or other HTML payloads, into the website. These scripts execute when any guest visits the affected page, potentially leading to data theft, defacement, or further compromise of the site compromise [1].

Mitigation

The vulnerability is patched in versions beyond 0.3.9. Users are strongly advised to update the Buckets plugin immediately. If updating is not possible, contacting a hosting provider or web developer for assistance is recommended [1].
