CVE-2025-26868

Vulnerability

Overview

The Fast Flow WordPress plugin contains a Reflected Cross-Site Scripting (XSS) vulnerability in the fast-flow-dashboard component. The root cause is improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary HTML and JavaScript [1]. This flaw affects all versions from n/a through 1.2.16.

Exploitation

Details

Exploitation requires user interaction; a privileged user must click on a crafted link, visit a specially prepared page, or submit a malicious form [1]. The attacker does not need authentication but relies on social engineering to trick a user with appropriate privileges into performing the action. No additional privileges beyond the ability to craft a URL or form are required.

Impact

Successful exploitation enables the attacker to inject arbitrary scripts and HTML payloads into the affected site [1]. This can be used to perform actions such as redirecting visitors to malicious websites, displaying advertisements, or stealing session cookies. The vulnerability is moderate in severity (CVSS 7.1) and is expected to be used in mass-exploit campaigns targeting thousands of websites [1].

Mitigation

The vendor has released version 1.2.18 which resolves the issue [1]. Users are strongly advised to update immediately, or enable auto-updates for the plugin. If immediate updating is not possible, the Patchstack advisory recommends applying a mitigation rule to block attacks, and users should consult their hosting provider for assistance [1].
