Unauthenticated Admin Account Creation in WooCommerce Plugin

The Spreadsheet Price Changer for WooCommerce and WP E-commerce – Light plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.4.37 vi the user_filter function. This makes it possible for unauthenticated attackers to create admin accounts.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2025-10656 is a critical authorization bypass vulnerability affecting the Spreadsheet Price Changer plugin for WordPress, used by e-commerce sites running WooCommerce and WP E-Commerce. The vulnerability exists in the user_filter function and allows unauthenticated attackers to create administrator accounts without any authentication checks. This is particularly dangerous because WordPress admin accounts have unrestricted access to site configuration, user data, and plugin management, making this a direct pathway to complete site compromise. Any WordPress installation using this plugin up to version 2.4.37 is at risk, potentially affecting thousands of e-commerce businesses that rely on this plugin for inventory management.

Casky's 283 mapped skills detect the attack patterns underlying this vulnerability by analyzing both MITRE ATT&CK tactics: TA0004 (Privilege Escalation) and TA0006 (Credential Access). Claude's extended reasoning identifies the authorization bypass chain—detecting when the user_filter function is called without proper capability verification, which maps to CWE-863 (Incorrect Authorization). Practitioners using Casky would see findings highlighting suspicious wp_create_user() calls originating from unauthenticated requests, missing current_user_can() checks in plugin code paths, and direct database user insertions circumventing WordPress role validation. The skills correlate these patterns to flag both the initial missing authorization check and the subsequent privilege escalation to admin, providing security teams with the complete attack narrative needed to prioritize remediation and identify potentially compromised accounts.
