CVE-2025-27279

Vulnerability

Description A reflected cross-site scripting (XSS) vulnerability exists in the Flashfader plugin for WordPress, affecting versions up to and including 1.1.1. The issue stems from improper neutralization of user input during web page generation, allowing attackers to inject arbitrary HTML and JavaScript code.

Exploitation

To exploit this vulnerability, an attacker must craft a malicious link containing the XSS payload and trick a privileged user (such as an administrator) into clicking it. User interaction is required for successful exploitation, as the victim must perform an action like clicking the link or visiting a crafted page [1].

Impact

Successful exploitation enables an attacker to inject malicious scripts, redirect visitors to malicious sites, display advertisements, or perform other unauthorized actions within the context of the affected WordPress site. This can lead to compromised site integrity and potential harm to visitors [1].

Mitigation

Users are advised to update the Flashfader plugin to a patched version as soon as it becomes available. In the interim, Patchstack has released a mitigation rule that can block attacks until an official fix is applied [1].
