CVE-2025-67546 is a security vulnerability identified in the WP ERP plugin developed by weDevs, affecting all versions up to and including 1.16.6. The vulnerability allows an unauthorized control sphere—meaning an attacker without proper authentication or privileges—to retrieve embedded sensitive system information from the affected ERP system. This exposure can include configuration details, system metadata, or other sensitive embedded data that could be leveraged to facilitate further attacks such as privilege escalation, targeted phishing, or lateral movement within an organization's network. The vulnerability was published on December 18, 2025, with no CVSS score assigned yet and no known exploits detected in the wild. The lack of a CVSS score suggests the vulnerability is newly disclosed and may not have been fully analyzed for impact or exploitability. WP ERP is a WordPress plugin widely used by small and medium enterprises (SMEs) to manage HR, CRM, and accounting functions. Since WordPress powers a significant portion of websites globally, including in Europe, the exposure of sensitive ERP data can have serious consequences for business operations and data privacy compliance. The vulnerability's technical details indicate that it allows retrieval of embedded sensitive data without proper authorization, implying a failure in access control mechanisms within the plugin. This could be due to improper validation of user permissions or insecure API endpoints. Although no patch links are currently provided, the vendor is expected to release updates to address this issue. Until patches are available, organizations must rely on compensating controls to mitigate risk.

The primary impact of CVE-2025-67546 is the unauthorized disclosure of sensitive system information, which compromises confidentiality. For European organizations, this can lead to exposure of business-critical data, configuration details, or personally identifiable information (PII), potentially violating GDPR and other data protection regulations. Such exposure can facilitate subsequent attacks, including privilege escalation, targeted social engineering, or exploitation of other vulnerabilities. The availability and integrity of systems are not directly impacted by this vulnerability, but the information leak can indirectly lead to more severe breaches. SMEs using WP ERP in Europe are particularly vulnerable due to the plugin's popularity in this segment. The breach of sensitive ERP data can disrupt business operations, damage reputation, and incur regulatory penalties. Given the lack of known exploits, immediate widespread impact is limited, but the vulnerability presents a significant risk if weaponized. Organizations in sectors with high regulatory scrutiny or handling sensitive customer data face heightened consequences. The vulnerability also poses risks to supply chain security if attackers gain insights into internal systems through exposed data.

1. Monitor the vendor's official channels for patches addressing CVE-2025-67546 and apply updates promptly once available. 2. Until patches are released, restrict access to WP ERP interfaces by IP whitelisting or VPN-only access to reduce exposure to unauthorized users. 3. Implement strict role-based access controls within WordPress and WP ERP to limit data visibility to authorized personnel only. 4. Conduct regular audits of user permissions and plugin configurations to detect and remediate misconfigurations. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting WP ERP endpoints. 6. Monitor logs for unusual access patterns or data retrieval attempts that could indicate exploitation attempts. 7. Educate administrators and users about the risks of exposing sensitive ERP data and encourage prompt reporting of anomalies. 8. Consider isolating the WP ERP environment from other critical systems to limit lateral movement in case of compromise. 9. Review and enhance overall WordPress security posture, including timely updates of core, themes, and plugins. 10. Prepare incident response plans that include scenarios involving data exposure from ERP systems.
