CVE-2025-48128 is a Missing Authorization vulnerability (CWE-862) identified in the Sharespine Woocommerce Connector, a plugin that integrates Woocommerce e-commerce platforms with Sharespine services. The vulnerability arises from incorrectly configured access control mechanisms, allowing users with limited privileges (PR:L - privileges required: low) to perform actions or access resources that should be restricted. Specifically, the flaw permits exploitation over the network (AV:N - attack vector: network) without requiring user interaction (UI:N), but does require some level of authenticated access. The vulnerability impacts versions up to 4.7.55, although exact affected versions are not fully enumerated. The CVSS v3.1 base score is 4.3, indicating a medium severity level, with the impact primarily on integrity (I:L) and no direct impact on confidentiality or availability. This means an attacker with low-level privileges could potentially modify data or configurations improperly due to missing authorization checks, but cannot directly compromise data confidentiality or cause denial of service. No known exploits are currently reported in the wild, and no patches have been linked yet. The issue was published on May 16, 2025, and has been enriched by CISA, indicating recognition by US cybersecurity authorities. The vulnerability is significant because Woocommerce is widely used in e-commerce, and Sharespine connectors facilitate critical business processes such as order and inventory synchronization. Improper authorization could lead to unauthorized data manipulation, impacting business operations and trustworthiness of e-commerce transactions.

For European organizations using Woocommerce integrated with Sharespine via this connector, the vulnerability poses a risk of unauthorized modification of e-commerce data such as orders, inventory levels, or pricing information. This could lead to financial discrepancies, customer dissatisfaction, and potential regulatory compliance issues under GDPR if data integrity is compromised. Although confidentiality is not directly impacted, integrity violations can undermine trust and operational continuity. Attackers with low-level access (e.g., a compromised low-privilege user account or automated scripts exploiting weak authentication) could exploit this flaw remotely without user interaction, increasing the risk of automated or large-scale attacks. European e-commerce businesses, especially SMEs relying on Woocommerce and Sharespine for backend integration, could face disruptions or financial losses. Additionally, supply chain partners relying on accurate data synchronization may be indirectly affected. The absence of known exploits currently reduces immediate risk but does not eliminate the potential for future exploitation, especially as awareness of the vulnerability spreads.

1. Immediate review and tightening of access control policies within the Sharespine Woocommerce Connector configuration to ensure that all sensitive operations require proper authorization checks. 2. Limit user privileges strictly to the minimum necessary, especially for accounts that interact with the connector. 3. Monitor logs for unusual activities or unauthorized attempts to access or modify data through the connector. 4. Implement network segmentation and firewall rules to restrict access to the connector endpoints only to trusted systems and users. 5. Coordinate with Sharespine for timely updates or patches addressing this vulnerability and apply them as soon as available. 6. Conduct penetration testing focused on authorization controls in the connector to identify any other potential weaknesses. 7. Educate administrators and users about the risks of privilege escalation and the importance of strong authentication practices. 8. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the connector's API endpoints. 9. Regularly back up e-commerce data to enable recovery in case of data integrity compromise.
