CVE-2025-9243 in Cost Calculator Builder Plugin
Summary
by MITRE • 10/04/2025
The Cost Calculator Builder plugin for WordPress is vulnerable to unauthorizedmodification of data due to a missing capability check on the get_cc_orders and update_order_status functions in all versions up to, and including, 3.5.32. This makes it possible for authenticated attackers, with Subscriber-level access and above, to access order management functions and modify order status.

The vulnerability identified as CVE-2025-9243 affects the Cost Calculator Builder plugin for WordPress, representing a critical authorization flaw that undermines the integrity of order management operations. This issue stems from insufficient capability verification within the plugin's core functionality, specifically impacting the get_cc_orders and update_order_status functions that are accessible to all authenticated users regardless of their privilege level. The flaw exists in all versions up to and including 3.5.32, making it a widespread concern across numerous installations. The vulnerability allows malicious actors with subscriber-level access or higher to exploit these functions and manipulate order statuses without proper authorization, creating potential for data integrity breaches and financial manipulation.
The technical implementation of this vulnerability demonstrates a classic lack of input validation and privilege enforcement within WordPress plugin architecture. The get_cc_orders function fails to verify whether the requesting user possesses adequate permissions to access order data, while the update_order_status function lacks proper capability checks before allowing modifications to order status values. This absence of authorization controls creates an attack vector that directly violates the principle of least privilege, where users should only have access to functions and data necessary for their role. The vulnerability operates at the application layer and can be exploited through authenticated sessions, making it particularly dangerous as it requires minimal escalation from existing user access.
From an operational perspective, this vulnerability presents significant risks to businesses utilizing the Cost Calculator Builder plugin for WordPress. Attackers with subscriber-level access can potentially manipulate order processing workflows, change payment statuses, and alter order fulfillment sequences, leading to financial losses and operational disruptions. The impact extends beyond simple data modification as it can affect inventory management, customer billing, and overall business continuity. The vulnerability is particularly concerning in e-commerce environments where order status tracking is critical for customer service, logistics coordination, and financial reconciliation processes. Additionally, the unauthorized modification capabilities could be leveraged for more sophisticated attacks including fraud detection bypassing or manipulation of customer order histories.
Security mitigations for this vulnerability should focus on immediate remediation through plugin updates to versions that implement proper capability checks. Organizations should conduct comprehensive audits of their WordPress installations to identify all affected plugin versions and ensure timely updates are deployed across all systems. Network segmentation and monitoring should be enhanced to detect unusual order modification patterns that might indicate exploitation attempts. The implementation of role-based access controls should be reviewed to ensure that only authorized personnel have access to order management functions, with proper logging and audit trails established for all order-related activities. This vulnerability aligns with CWE-285 which addresses improper authorization in software systems, and represents a specific instance of ATT&CK technique T1078 which covers valid accounts and privilege escalation through unauthorized access to system functions. Organizations should also consider implementing additional security controls such as web application firewalls and regular security assessments to prevent similar authorization bypass vulnerabilities from occurring in other plugin components or custom WordPress functionality.
