DescriptionCVE.org

Incorrect Privilege Assignment vulnerability in Rymera Web Co Pty Ltd. Woocommerce Wholesale Lead Capture allows Privilege Escalation.This issue affects Woocommerce Wholesale Lead Capture: from n/a through 2.0.3.1.

AnalysisAI

An incorrect privilege assignment vulnerability exists in the WooCommerce Wholesale Lead Capture plugin for WordPress, allowing unauthenticated attackers to escalate privileges on affected sites. All versions through 2.0.3.1 of the plugin developed by Rymera Web Co Pty Ltd. are vulnerable. With a CVSS score of 9.8 (Critical) and network-based exploitation requiring no privileges or user interaction, this represents a severe security risk for WordPress sites using this plugin.

Technical ContextAI

This vulnerability affects the WooCommerce Wholesale Lead Capture plugin (cpe:2.3:a:rymera_web_co_pty_ltd.:woocommerce_wholesale_lead_capture), a WordPress plugin used to capture wholesale lead information for WooCommerce stores. The root cause is classified under CWE-266 (Incorrect Privilege Assignment), which occurs when software does not properly restrict or incorrectly assigns privileges to actors, allowing them to perform actions they should not be authorized to execute. In WordPress plugins, this typically manifests as insufficient capability checks on administrative functions, allowing lower-privileged or unauthenticated users to execute privileged operations such as user role modification, settings changes, or data manipulation.

RemediationAI

Site administrators should immediately upgrade the WooCommerce Wholesale Lead Capture plugin to a patched version newer than 2.0.3.1 if available from the vendor or WordPress plugin repository. Consult the Patchstack database entry at https://patchstack.com/database/wordpress/plugin/woocommerce-wholesale-lead-capture/vulnerability/wordpress-woocommerce-wholesale-lead-capture-plugin-1-17-8-privilege-escalation-vulnerability?_s_id=cve for specific remediation guidance and patched version information. If a patch is not yet available or cannot be applied immediately, consider temporarily disabling the plugin and removing it from the WordPress installation until a fix is deployed, especially if the wholesale lead capture functionality is not business-critical. Additionally, implement web application firewall (WAF) rules to restrict access to the plugin's endpoints, monitor WordPress user creation and role modification activities, and conduct a security audit to verify no unauthorized privilege escalation has already occurred.
