CVE-2025-48129: WooCommerce Price Changer Privilege Escalation

CVE-2025-48129 Overview

CVE-2025-48129 is an Incorrect Privilege Assignment vulnerability affecting the Spreadsheet Price Changer for WooCommerce and WP E-commerce – Light plugin developed by Holest Engineering. This vulnerability allows unauthenticated attackers to escalate privileges on affected WordPress installations running vulnerable versions of the plugin.

The flaw stems from improper privilege assignment (CWE-266), enabling malicious actors to gain elevated access without requiring authentication. Given the plugin's role in managing WooCommerce pricing through spreadsheet functionality, successful exploitation could grant attackers administrative control over e-commerce operations.

Critical Impact

Unauthenticated attackers can exploit this privilege escalation vulnerability to gain administrative access to WordPress sites running the vulnerable plugin, potentially compromising the entire e-commerce platform.

Affected Products

• Spreadsheet Price Changer for WooCommerce and WP E-commerce – Light versions through 2.4.37
• WordPress installations running the vulnerable plugin
• WooCommerce and WP E-commerce platforms integrated with the affected plugin

Technical Details for CVE-2025-48129

Vulnerability Analysis

This vulnerability is classified as an Incorrect Privilege Assignment (CWE-266) issue within the Spreadsheet Price Changer plugin. The flaw allows attackers to bypass normal authentication and authorization mechanisms, resulting in unauthorized privilege escalation. The vulnerability is exploitable remotely over the network without requiring any prior authentication or user interaction, making it particularly dangerous for exposed WordPress installations.

The attack can result in complete compromise of the affected system's confidentiality, integrity, and availability. Attackers gaining elevated privileges could manipulate product pricing, access sensitive customer data, install malicious plugins, or take full administrative control of the WordPress site.

Root Cause

The root cause of CVE-2025-48129 lies in improper privilege assignment within the plugin's codebase. The Spreadsheet Price Changer plugin fails to properly validate user privileges before allowing access to sensitive functionality. This incorrect privilege assignment allows users without appropriate permissions to perform actions that should be restricted to administrators or other privileged roles.

Specifically, the plugin does not adequately check user capabilities before processing requests, allowing unauthenticated users to access privileged functionality intended only for site administrators.

Attack Vector

The vulnerability is exploitable via network-based attacks with low complexity requirements. An attacker does not need any prior privileges or user interaction to exploit this vulnerability. The attack flow typically involves:

1. An attacker identifies a WordPress site running the vulnerable Spreadsheet Price Changer plugin (versions through 2.4.37)
2. The attacker crafts malicious requests targeting the plugin's improperly protected endpoints
3. Due to incorrect privilege assignment, the plugin processes these requests without proper authorization checks
4. The attacker successfully escalates privileges, potentially gaining administrative access to the WordPress installation
