CVE-2025-48320: Baidu Share Button CSRF Vulnerability

CVE-2025-48320 is a Cross-Site Request Forgery flaw in the Baidu Share Button WordPress plugin that enables stored XSS attacks. This article covers the technical details, affected versions up to 1.0.6, and mitigation.

Updated: May 15, 2026

CVE-2025-48320 Overview

CVE-2025-48320 is a Cross-Site Request Forgery (CSRF) vulnerability in the baidushare-wp WordPress plugin (百度分享按钮) developed by cuckoohello. The flaw affects all plugin versions up to and including 1.0.6. An attacker can chain the CSRF weakness with stored Cross-Site Scripting (XSS), allowing malicious JavaScript to be persisted in the WordPress site when an authenticated administrator is tricked into visiting an attacker-controlled page. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.

Critical Impact

A successful attack persists attacker-controlled JavaScript inside the WordPress admin context, enabling session theft, administrative action abuse, and site-wide visitor compromise.

Affected Products

  • cuckoohello 百度分享按钮 (baidushare-wp) WordPress plugin versions up to and including 1.0.6
  • WordPress sites with the plugin installed and an authenticated administrator session
  • No fixed version is referenced in the available advisory data

Technical Details for CVE-2025-48320

Vulnerability Analysis

The baidushare-wp plugin exposes a state-changing administrative action that lacks proper CSRF protection. The handler does not validate a WordPress nonce or verify the origin of the inbound request before persisting user-supplied input. An attacker hosts a crafted page or form that submits a forged request to the plugin's settings endpoint. When a logged-in administrator visits the malicious page, the browser automatically sends authenticated cookies, and WordPress executes the request under the administrator's privileges.

The injected payload is stored in plugin configuration and later rendered without sufficient output escaping. This converts the CSRF primitive into a stored XSS condition. Any subsequent visitor or administrator who loads a page containing the affected output executes the attacker's JavaScript. User interaction is required, which is reflected in the attack vector requiring a victim to click or load the attacker's URL.

Root Cause

The root cause is missing CSRF token validation on a privileged plugin action combined with inadequate sanitization of stored input. The plugin trusts the authenticated session state without verifying the request's authenticity through a wp_nonce check or capability re-validation. Output rendering does not apply esc_html, esc_attr, or equivalent context-aware encoding, allowing HTML and script content to survive into the DOM.

Attack Vector

Exploitation is network-based and requires social engineering to land an administrator on an attacker-controlled page. The attacker prepares an HTML form or fetch call targeting the vulnerable plugin endpoint with a malicious payload such as a <script> tag in a settings field. Once submitted by the victim's browser, the payload is persisted. When the plugin renders the stored content on the front end or admin dashboard, the script executes in the victim's browser context. Refer to the Patchstack Vulnerability Advisory for additional technical context.

Detection Methods for CVE-2025-48320

Indicators of Compromise

  • Unexpected <script>, <iframe>, or event-handler attributes inside plugin settings stored in the wp_options table for baidushare-wp keys
  • Outbound HTTP requests from visitor browsers to unknown domains shortly after pages containing Baidu share buttons load
  • Administrator referrer logs showing settings changes originating from non-WordPress domains

Detection Strategies

  • Review the WordPress database for plugin option values containing HTML markup or JavaScript constructs that are not part of legitimate configuration
  • Inspect web server access logs for POST requests to wp-admin/admin.php or wp-admin/options.php referencing baidushare-wp parameters with external referers
  • Use a web application firewall to flag form submissions to plugin endpoints that lack a valid WordPress nonce parameter

Monitoring Recommendations

  • Monitor administrator account activity for configuration changes performed outside expected maintenance windows
  • Alert on Content Security Policy (CSP) violations reported from pages where the plugin renders share buttons
  • Track plugin file modification times and compare against the installed version manifest to detect tampering

How to Mitigate CVE-2025-48320

Immediate Actions Required

  • Deactivate and remove the baidushare-wp plugin until a vendor patch is confirmed available
  • Audit the wp_options table and plugin-specific settings for injected scripts and remove any stored payloads
  • Force a password reset and re-authentication for all WordPress administrator accounts
  • Review recent administrator activity logs for unauthorized configuration changes

Patch Information

No vendor-supplied patch is referenced in the available advisory data for CVE-2025-48320. The vulnerability affects versions up to and including 1.0.6. Site operators should consult the Patchstack Vulnerability Advisory for updates and consider replacing the plugin with an actively maintained alternative.

Workarounds

  • Restrict access to /wp-admin/ by IP allowlist or VPN to limit exposure of administrator sessions
  • Deploy a web application firewall rule that blocks POST requests to plugin endpoints lacking a valid _wpnonce parameter
  • Apply a strict Content Security Policy that disallows inline scripts to reduce the impact of stored XSS
  • Train administrators to log out of WordPress before browsing untrusted sites and to use isolated browser profiles for admin work
bash
# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate baidushare-wp
wp plugin delete baidushare-wp

# Audit options table for suspicious script content
wp db query "SELECT option_name, option_value FROM wp_options WHERE option_name LIKE '%baidushare%' AND option_value LIKE '%<script%';"
