CVE-2025-23990: Scroll Styler CSRF Vulnerability

CVE-2025-23990 Overview

CVE-2025-23990 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Scroll Styler WordPress plugin developed by jablonczay. This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by tricking them into visiting a malicious webpage. The vulnerability can be chained with Stored Cross-Site Scripting (XSS), enabling attackers to inject persistent malicious scripts into the WordPress site.

Critical Impact

Attackers can leverage this CSRF vulnerability to perform unauthorized administrative actions and inject stored XSS payloads, potentially compromising the entire WordPress installation and its visitors.

Affected Products

• Scroll Styler WordPress plugin version 1.1 and earlier
• WordPress installations running vulnerable Scroll Styler versions

Technical Details for CVE-2025-23990

Vulnerability Analysis

This vulnerability exists due to missing or improper CSRF token validation in the Scroll Styler plugin's administrative functions. When a WordPress administrator visits a malicious page crafted by an attacker, the browser automatically includes the administrator's session cookies with any requests made to the WordPress site. Without proper CSRF protection, the plugin processes these requests as legitimate administrative actions.

The vulnerability is particularly severe because it can be chained with Stored XSS. An attacker can craft a malicious request that not only bypasses CSRF protections but also injects JavaScript code that gets stored in the WordPress database. This stored payload executes whenever other users or administrators view the affected pages, creating a persistent attack vector.

The attack requires user interaction (a victim must click a malicious link or visit a compromised page), but requires no authentication from the attacker. The scope of impact extends beyond the vulnerable component, potentially affecting the confidentiality, integrity, and availability of the entire WordPress installation.

Root Cause

The root cause is improper implementation of anti-CSRF mechanisms (CWE-352) in the Scroll Styler plugin. The plugin fails to validate nonce tokens or implement other CSRF protection measures on sensitive administrative endpoints. This allows attackers to craft requests that the server cannot distinguish from legitimate user-initiated actions.

Attack Vector

The attack is network-based and follows these steps:

1. The attacker identifies a WordPress site running a vulnerable version of Scroll Styler (<= 1.1)
2. The attacker crafts a malicious HTML page containing a hidden form or JavaScript that submits requests to the target WordPress admin endpoints
3. The attacker tricks an authenticated WordPress administrator into visiting the malicious page (via phishing, social engineering, or compromised websites)
4. When the administrator visits the page, their browser automatically sends the malicious request along with valid session cookies
5. The Scroll Styler plugin processes the request without verifying its origin, executing the attacker's commands
6. If combined with XSS payload injection, malicious scripts become persistently stored and execute for all site visitors

The vulnerability does not require any specific exploitation code as it leverages standard web request mechanisms. Technical details regarding the specific vulnerable endpoints can be found in the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-23990

Indicators of Compromise

• Unexpected changes to Scroll Styler plugin settings without administrator action
• Suspicious JavaScript code injected into WordPress pages or database entries
• Unauthorized plugin configuration modifications in WordPress audit logs
• Reports from site visitors experiencing unusual redirects or popup behaviors

Detection Strategies

• Monitor WordPress admin activity logs for configuration changes to the Scroll Styler plugin
• Implement Web Application Firewall (WAF) rules to detect cross-origin form submissions to WordPress admin endpoints
• Scan WordPress database for unexpected script tags or JavaScript in plugin-related option values
• Review HTTP referrer headers in server logs for requests to plugin admin pages from external domains

Monitoring Recommendations

• Enable comprehensive WordPress audit logging to track all plugin setting modifications
• Configure alerts for any changes to Scroll Styler plugin options outside of expected maintenance windows
• Implement Content Security Policy (CSP) headers to detect and report XSS payload execution
• Regularly scan the WordPress installation with security plugins capable of detecting stored XSS

How to Mitigate CVE-2025-23990

Immediate Actions Required

• Audit current Scroll Styler plugin settings for any unauthorized modifications
• Deactivate and remove the Scroll Styler plugin if no patched version is available
• Review WordPress database for any injected malicious scripts in plugin-related options
• Clear browser caches for all administrative users who may have been exposed

Patch Information

At the time of this advisory, administrators should check the WordPress plugin repository for any updated versions of Scroll Styler that address this vulnerability. If no patch is available, consider alternative plugins with proper CSRF protection implemented. Refer to the Patchstack Vulnerability Report for the latest patching information.

Workarounds

• Remove or deactivate the Scroll Styler plugin until a security patch is released
• Implement a Web Application Firewall (WAF) with rules to block cross-origin POST requests to WordPress admin endpoints
• Restrict access to WordPress admin panel by IP address where feasible
• Train administrators to avoid clicking unknown links while logged into WordPress
• Consider using browser extensions that provide additional CSRF protection for administrative sessions

# WordPress CLI command to deactivate the vulnerable plugin
wp plugin deactivate scroll-styler

# Verify the plugin is deactivated
wp plugin list --status=inactive | grep scroll-styler

# Optional: Remove the plugin entirely until patched
wp plugin delete scroll-styler
