CVE-2025-59580 is an Incorrect Privilege Assignment vulnerability found in the GoodLayers Core plugin, affecting all versions prior to 2.1.7. This vulnerability allows an attacker who already has some level of privileges (PR:L) to escalate their permissions without requiring user interaction (UI:N). The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), meaning it can be exploited easily by a remote attacker with limited privileges. The scope of the vulnerability is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that successful exploitation could lead to full system compromise, data leakage, unauthorized modifications, and service disruption. The vulnerability arises from improper assignment of privileges within the GoodLayers Core plugin, which is commonly used in WordPress environments for theme and page builder functionalities. Although no active exploits have been reported yet, the high CVSS score and ease of exploitation make this a critical issue. The vulnerability was reserved in September 2025 and published in October 2025, indicating recent discovery and disclosure. The lack of patch links suggests that users should monitor vendor announcements closely for updates or patches. Organizations relying on GoodLayers Core should audit their installations and privilege configurations to prevent unauthorized privilege escalation.

For European organizations, this vulnerability poses a significant risk, especially those using GoodLayers Core in their WordPress-based websites or digital platforms. Exploitation could allow attackers to escalate privileges from low-level user accounts to administrative control, leading to data breaches, defacement, or full system takeover. This could disrupt business operations, damage reputation, and lead to regulatory non-compliance under GDPR due to potential data exposure. The network-based attack vector means that attackers do not need physical or local access, increasing the threat surface. Sectors such as e-commerce, government portals, and media companies that rely heavily on WordPress and GoodLayers Core are particularly vulnerable. The high impact on confidentiality, integrity, and availability means that sensitive customer data, internal communications, and service availability could be compromised, resulting in financial losses and legal consequences.

Immediate mitigation involves upgrading GoodLayers Core to version 2.1.7 or later once the patch is released by the vendor. Until a patch is available, organizations should restrict access to the WordPress admin panel and limit user privileges to the minimum necessary. Conduct a thorough audit of user roles and permissions within WordPress to identify and remove any excessive privileges. Implement network-level protections such as web application firewalls (WAFs) to detect and block suspicious privilege escalation attempts targeting GoodLayers Core endpoints. Monitor logs for unusual privilege changes or access patterns. Consider isolating critical WordPress instances and applying strict access controls. Regularly back up website data and configurations to enable quick recovery in case of compromise. Stay informed through vendor advisories and security communities for updates or exploit reports. Finally, educate administrators and developers about the risks of privilege misconfiguration and the importance of timely patching.
