CVE-2025-58877 identifies a Missing Authorization vulnerability in the Javo Core plugin developed by javothemes, affecting versions up to and including 3.0.0.529. This vulnerability arises from incorrectly configured access control security levels within the plugin, which can allow attackers to bypass authorization checks. Essentially, certain functionalities or data that should be restricted to authorized users may be accessible without proper permissions. This can lead to unauthorized information disclosure, modification, or other malicious actions depending on the plugin's role within the hosting WordPress site. The vulnerability does not require user interaction or authentication to exploit, increasing its risk profile. Although no known exploits have been reported in the wild as of now, the flaw's presence in a widely used WordPress plugin component makes it a significant concern. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability affects confidentiality and integrity primarily, with potential availability impact depending on the misuse of the unauthorized access. The plugin's role in managing themes and site content means attackers could manipulate site appearance, content, or functionality, potentially leading to reputational damage or further compromise. The vulnerability was reserved in September 2025 and published in December 2025, indicating recent discovery and disclosure. No official patches or mitigation links are currently provided, emphasizing the need for vigilance and proactive security measures.

For European organizations, the impact of CVE-2025-58877 can be significant, especially for those relying on WordPress websites utilizing the Javo Core plugin. Unauthorized access due to missing authorization can lead to data breaches, unauthorized content changes, or privilege escalation within the website environment. This can result in loss of customer trust, regulatory non-compliance (notably GDPR), and potential financial losses. The integrity of website content and user data may be compromised, affecting business operations and brand reputation. Additionally, attackers could leverage this vulnerability as a foothold for further attacks, including malware deployment or lateral movement within the network. Organizations in sectors such as e-commerce, media, and public services, which often use WordPress extensively, are particularly vulnerable. The absence of known exploits currently provides a window for mitigation, but the ease of exploitation due to missing authorization controls means the threat could rapidly escalate once weaponized. The impact is heightened in Europe due to strict data protection regulations and the critical role of web presence in business and government services.

1. Monitor javothemes official channels and security advisories for patches addressing CVE-2025-58877 and apply them promptly once available. 2. Conduct a thorough audit of access control configurations within the Javo Core plugin and the broader WordPress environment to identify and rectify any misconfigurations. 3. Implement strict role-based access controls (RBAC) and principle of least privilege for all users interacting with the WordPress backend. 4. Use Web Application Firewalls (WAF) with custom rules to detect and block unauthorized access attempts targeting the plugin's endpoints. 5. Regularly review and monitor logs for unusual access patterns or unauthorized actions related to the plugin. 6. Consider temporarily disabling or restricting the Javo Core plugin if immediate patching is not possible and the plugin is not critical to operations. 7. Educate site administrators and developers about the risks of missing authorization vulnerabilities and best practices for secure plugin management. 8. Employ security scanning tools that can detect missing authorization issues in web applications to proactively identify similar vulnerabilities.
