CVE-2025-58877 is a missing authorization vulnerability identified in the Javo Core plugin developed by javothemes, affecting all versions up to and including 3.0.0.529. The core issue stems from incorrectly configured access control security levels within the plugin, which fail to properly restrict access to certain functionalities or data endpoints. This misconfiguration allows unauthenticated remote attackers to bypass authorization checks and access sensitive information that should otherwise be protected. The vulnerability does not require any privileges or user interaction to exploit, making it accessible to any remote attacker with network access to the affected web application. The CVSS 3.1 base score of 7.5 reflects a high severity rating primarily due to the confidentiality impact, as attackers can obtain sensitive data without affecting system integrity or availability. The vulnerability is network exploitable (AV:N), requires low attack complexity (AC:L), and no privileges or user interaction (PR:N/UI:N). Although no public exploits have been reported yet, the nature of the flaw suggests it could be weaponized quickly once details become widely known. Javo Core is a WordPress plugin used to enhance website functionality, and its presence on numerous sites increases the attack surface. The lack of available patches at the time of disclosure necessitates immediate attention to access control configurations and monitoring to mitigate risk until official fixes are released.

For European organizations, the primary impact of CVE-2025-58877 is unauthorized disclosure of sensitive data hosted on websites using the vulnerable Javo Core plugin. This could include customer information, internal business data, or other confidential content, potentially leading to reputational damage, regulatory penalties under GDPR, and loss of customer trust. Since the vulnerability does not affect integrity or availability, direct disruption of services or data manipulation is less likely. However, data breaches alone can have severe financial and legal consequences. Organizations relying on WordPress sites with Javo Core integrated may face targeted attacks exploiting this flaw, especially if they have not implemented compensating controls. The ease of exploitation without authentication increases the risk of automated scanning and mass exploitation campaigns. European entities in sectors such as e-commerce, media, and professional services that commonly use WordPress themes and plugins could be particularly vulnerable. Failure to remediate promptly could also expose organizations to compliance violations and increased scrutiny from data protection authorities.

1. Monitor official javothemes channels and security advisories for patches addressing CVE-2025-58877 and apply updates immediately upon release. 2. Until patches are available, restrict access to the affected plugin’s endpoints using web application firewalls (WAFs) or server-level access controls to limit exposure to trusted IPs only. 3. Conduct thorough audits of access control configurations within the Javo Core plugin settings to identify and correct any misconfigurations. 4. Implement enhanced logging and monitoring to detect unusual access patterns or unauthorized attempts targeting the plugin’s functionality. 5. Consider temporarily disabling or removing the Javo Core plugin if it is not critical to website operations, to eliminate the attack vector. 6. Educate website administrators on the risks of missing authorization vulnerabilities and best practices for plugin management. 7. Employ network segmentation and least privilege principles to minimize the impact scope if exploitation occurs. 8. Review and update incident response plans to include scenarios involving unauthorized data access via web application vulnerabilities.
