CVE-2025-58627 is a critical security vulnerability identified in the kamleshyadav Miraculous Core Plugin, affecting all versions prior to 2.0.9. The vulnerability arises from an authorization bypass caused by a user-controlled key that improperly influences access control security levels within the plugin. This misconfiguration allows an unauthenticated attacker to bypass authorization checks remotely without any user interaction, granting them full access to sensitive functions or data. The vulnerability impacts confidentiality, integrity, and availability, as attackers can potentially access or modify protected resources and disrupt services. The CVSS 3.1 base score of 9.8 reflects the high severity, with metrics indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits have been reported yet, the vulnerability's characteristics make it highly exploitable. The plugin is commonly used in WordPress environments, which are widespread in Europe, increasing the potential attack surface. The lack of patches at the time of publication necessitates urgent attention to mitigate risks. This vulnerability exemplifies the critical importance of correctly implementing access control mechanisms and validating user inputs that influence authorization decisions.

For European organizations, the impact of CVE-2025-58627 is substantial. Exploitation can lead to unauthorized access to sensitive information, data manipulation, and complete service disruption, which can affect business continuity and regulatory compliance, especially under GDPR. Organizations relying on the Miraculous Core Plugin for website functionality or security features risk compromise of their web infrastructure. The breach of confidentiality could expose personal data of European citizens, triggering legal and reputational consequences. Integrity violations may allow attackers to alter website content or configurations, potentially facilitating further attacks or misinformation. Availability impacts could result in denial of service, harming customer trust and operational capabilities. Given the plugin’s integration in WordPress sites, which are prevalent across Europe, the threat could affect a wide range of sectors including e-commerce, government, education, and healthcare. The critical severity and ease of exploitation elevate the urgency for European entities to assess their exposure and implement mitigations promptly.

1. Immediate action should be to monitor for the release of an official patch from the kamleshyadav Miraculous Core Plugin developers and apply it as soon as it becomes available. 2. In the interim, restrict access to the plugin’s administrative interfaces and sensitive endpoints using network-level controls such as IP whitelisting or VPN access. 3. Conduct a thorough review of access control configurations within the plugin and the hosting WordPress environment to ensure no user-controlled inputs influence authorization decisions. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests that attempt to manipulate keys or access control parameters. 5. Enable detailed logging and monitoring to identify anomalous access patterns indicative of exploitation attempts. 6. Educate site administrators about the risks and signs of exploitation related to this vulnerability. 7. Consider isolating or temporarily disabling the plugin if patching is delayed and the risk is deemed unacceptable. 8. Regularly audit all plugins and dependencies for vulnerabilities and maintain an up-to-date inventory to facilitate rapid response.
