CVE-2024-54439 Overview
CVE-2024-54439 is a Cross-Site Request Forgery (CSRF) vulnerability in the Alok Tiwari Amazon Product Price plugin for WordPress. The flaw affects all versions of the amazon-product-price plugin up to and including version 1.1. Successful exploitation chains CSRF into Stored Cross-Site Scripting (XSS), allowing attackers to persist malicious JavaScript within the affected site. The weakness is classified under CWE-352, reflecting missing or insufficient request origin validation. Exploitation requires user interaction, such as an authenticated administrator clicking an attacker-crafted link.
Critical Impact
An unauthenticated attacker can trick an authenticated administrator into submitting a forged request that injects persistent JavaScript, leading to session theft, account takeover, or further site compromise.
Affected Products
- Alok Tiwari Amazon Product Price plugin for WordPress
- All versions from initial release through 1.1
- WordPress sites with the amazon-product-price plugin installed and active

Technical Details for CVE-2024-54439
Vulnerability Analysis
The Amazon Product Price plugin fails to validate the origin of state-changing requests submitted to plugin administration endpoints. Without CSRF tokens or equivalent anti-forgery controls, the plugin accepts requests forged by external sites. When an authenticated administrator visits an attacker-controlled page, the browser silently submits a request containing attacker-supplied payload data. The plugin stores this input without proper output encoding or sanitization, persisting the payload in the WordPress database. Subsequent page renders execute the injected JavaScript in the browser of any visitor or administrator viewing the affected content.
Root Cause
The root cause is the absence of CSRF protection on plugin form handlers, combined with insufficient sanitization of stored input. WordPress provides nonce functions such as wp_nonce_field() and check_admin_referer() to mitigate CSRF, but the plugin does not invoke these controls on its administrative actions. The downstream output also lacks contextual escaping using functions such as esc_html() or esc_attr(), enabling the stored XSS condition.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a malicious page or sends a crafted link to a WordPress administrator. When the administrator, with an active session on the target site, visits the attacker page, their browser issues a forged POST request to the vulnerable plugin endpoint. The forged request writes attacker-controlled JavaScript into plugin-managed content. The payload then executes in the context of the WordPress site every time the affected page is rendered. Refer to the Patchstack Vulnerability Report for additional technical details.
Detection Methods for CVE-2024-54439
Indicators of Compromise
- Unexpected <script> tags, event handlers, or obfuscated JavaScript stored in plugin-managed posts, options, or metadata
- WordPress administrator sessions that perform plugin configuration changes without a corresponding referer from the WordPress admin dashboard
- Outbound requests from visitor browsers to unfamiliar domains after loading pages that render Amazon Product Price content
- New or modified administrator accounts created shortly after an administrator clicked an external link
Detection Strategies
- Inspect database tables such as wp_posts, wp_postmeta, and wp_options for stored HTML or JavaScript payloads referencing the amazon-product-price plugin
- Review web server access logs for POST requests to plugin endpoints lacking a same-origin Referer header
- Deploy Content Security Policy (CSP) reporting to surface unexpected inline script execution on pages using the plugin
Monitoring Recommendations
- Enable file integrity monitoring on the wp-content/plugins/amazon-product-price/ directory
- Alert on administrator-level requests that modify plugin options outside of normal maintenance windows
- Continuously scan rendered pages for unauthorized script tags using an external DOM monitoring tool
How to Mitigate CVE-2024-54439
Immediate Actions Required
- Deactivate and remove the Amazon Product Price plugin from any WordPress installation running version 1.1 or earlier until a patched release is confirmed
- Audit all content and options stored by the plugin and remove any unauthorized HTML or JavaScript payloads
- Force a password reset and session invalidation for all administrator accounts that may have been targeted
- Review recent administrative actions in WordPress audit logs for unauthorized changes
Patch Information
No fixed version is listed in the available advisory data. The vulnerability affects the plugin from initial release through version 1.1. Monitor the Patchstack advisory and the WordPress plugin repository for an updated release that introduces CSRF nonces and proper output escaping.
Workarounds
- Remove the plugin entirely if vendor patches remain unavailable, and replace it with an actively maintained alternative
- Restrict access to wp-admin using IP allow-lists or VPN to reduce the chance of CSRF exposure from external pages
- Deploy a web application firewall rule that blocks POST requests to plugin endpoints without a valid same-origin Referer and WordPress nonce
- Enforce a strict Content Security Policy that disallows inline scripts to limit Stored XSS impact
# Configuration example: remove the vulnerable plugin via WP-CLI
wp plugin deactivate amazon-product-price
wp plugin delete amazon-product-price
