CVE-2025-23710: Flying Twitter Birds CSRF Vulnerability

CVE-2025-23710 Overview

CVE-2025-23710 is a Cross-Site Request Forgery (CSRF) vulnerability in the Flying Twitter Birds WordPress plugin developed by Mayur Sojitra. This vulnerability allows attackers to chain CSRF with Stored Cross-Site Scripting (XSS), enabling malicious actors to inject persistent scripts into the WordPress site when an authenticated administrator is tricked into performing unintended actions.

Critical Impact

Attackers can leverage this CSRF-to-Stored-XSS chain to persistently compromise WordPress sites, potentially stealing administrator credentials, hijacking sessions, or injecting malicious content visible to all site visitors.

Affected Products

• Flying Twitter Birds WordPress Plugin version 1.8 and earlier
• WordPress installations using the flying-twitter-birds plugin

Technical Details for CVE-2025-23710

Vulnerability Analysis

This vulnerability combines two attack vectors: Cross-Site Request Forgery (CSRF) and Stored Cross-Site Scripting (XSS). The Flying Twitter Birds plugin fails to implement proper CSRF token validation on its administrative settings forms. This missing protection allows attackers to craft malicious requests that, when executed by an authenticated administrator, modify plugin settings to include malicious JavaScript payloads.

The Stored XSS component means that the injected malicious scripts persist in the plugin's configuration and execute whenever the affected pages are loaded. This creates a persistent attack vector that affects all visitors to the compromised WordPress site, not just the initial victim.

Root Cause

The root cause of CVE-2025-23710 lies in the absence of nonce verification in the plugin's settings update functionality. WordPress provides the wp_nonce_field() and wp_verify_nonce() functions specifically to prevent CSRF attacks, but the Flying Twitter Birds plugin does not properly implement these security controls. Additionally, the plugin fails to sanitize user input before storing it in the database and does not escape output when rendering the settings, enabling the Stored XSS attack chain.

Attack Vector

The attack requires network access and user interaction to exploit. An attacker crafts a malicious HTML page containing a hidden form that automatically submits a request to the vulnerable plugin's settings endpoint. When an authenticated WordPress administrator visits this malicious page, the browser automatically sends the forged request with the administrator's session cookies, bypassing authentication requirements.

The malicious payload typically includes JavaScript code injected into plugin configuration fields. Once stored, this script executes in the context of any user viewing pages where the plugin renders its output, potentially enabling session hijacking, credential theft, defacement, or redirection to malicious sites.

Detection Methods for CVE-2025-23710

Indicators of Compromise

• Unexpected modifications to Flying Twitter Birds plugin settings without administrator action
• JavaScript code present in plugin configuration database entries
• Suspicious administrator activity logs showing settings changes at unexpected times or from unfamiliar IP addresses
• User reports of browser warnings, redirects, or unusual behavior on pages using the plugin

Detection Strategies

• Review WordPress database for unexpected script tags or JavaScript in the flying-twitter-birds plugin options
• Monitor HTTP access logs for POST requests to plugin settings endpoints from external referrers
• Implement Web Application Firewall (WAF) rules to detect and block CSRF and XSS attack patterns
• Utilize WordPress security plugins that scan for stored XSS payloads in plugin configurations

Monitoring Recommendations

• Enable comprehensive logging for WordPress administrative actions, particularly plugin settings modifications
• Deploy client-side monitoring to detect anomalous JavaScript execution patterns
• Regularly audit plugin configurations for unauthorized changes
• Implement Content Security Policy (CSP) headers to mitigate XSS impact

How to Mitigate CVE-2025-23710

Immediate Actions Required

• Disable or remove the Flying Twitter Birds plugin (flying-twitter-birds) immediately if running version 1.8 or earlier
• Review plugin settings in the WordPress database for any injected malicious code
• Audit administrator accounts for signs of compromise or unauthorized access
• Clear browser caches for administrators who may have accessed malicious pages
• Consider resetting administrator credentials as a precaution

Patch Information

At the time of this writing, no official patch has been confirmed for this vulnerability. Website administrators should check the Patchstack Vulnerability Report for updated remediation guidance and monitor the WordPress plugin repository for security updates.

Workarounds

• Deactivate and remove the Flying Twitter Birds plugin until a patched version is available
• Implement a Web Application Firewall (WAF) with CSRF and XSS protection rules
• Restrict administrative access to trusted IP addresses using .htaccess or server-level firewall rules
• Add Content Security Policy (CSP) headers to prevent inline script execution and mitigate XSS attacks
• Use browser extensions that provide CSRF protection for administrators managing WordPress sites

# Example .htaccess rules to restrict wp-admin access by IP
<Files wp-login.php>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.100
</Files>
