CVE-2025-62946 identifies a missing authorization vulnerability in the Everest Backup plugin developed by everestthemes, affecting all versions up to and including 2.3.8. The vulnerability arises from improperly configured access control security levels, which fail to enforce proper authorization checks on backup-related operations. This misconfiguration permits attackers to bypass intended restrictions, potentially allowing unauthorized users to perform backup management tasks such as creating, restoring, or deleting backups without proper credentials. Although no public exploits have been reported, the nature of the vulnerability suggests that exploitation could be straightforward, as it does not require authentication or user interaction. The plugin is commonly used in WordPress environments to manage website backups, making it a critical component for data integrity and availability. The absence of a CVSS score indicates that the vulnerability is newly disclosed and pending detailed severity assessment. However, the missing authorization flaw directly threatens the confidentiality, integrity, and availability of backup data, which is essential for disaster recovery and business continuity. Attackers exploiting this vulnerability could access sensitive data contained in backups or disrupt backup processes, leading to potential data loss or exposure. The vulnerability was published on October 27, 2025, with no patches currently linked, emphasizing the need for immediate attention from users of Everest Backup. Organizations relying on this plugin should conduct thorough access control reviews and monitor backup operations for anomalies. The vulnerability's impact is amplified in environments where backups contain sensitive or regulated data, common in European enterprises.

For European organizations, the impact of CVE-2025-62946 can be significant due to the critical role backups play in data protection and regulatory compliance such as GDPR. Unauthorized access to backup data can lead to exposure of personal and sensitive information, risking privacy violations and potential legal penalties. Integrity of backups may be compromised, allowing attackers to inject malicious data or delete backups, which can disrupt recovery efforts after incidents like ransomware attacks. Availability of backup services may also be affected if attackers manipulate backup operations, causing downtime or data loss. Given the widespread use of WordPress and associated plugins like Everest Backup across Europe, organizations in sectors such as finance, healthcare, and government are particularly vulnerable. The lack of authentication requirements for exploitation increases the risk of automated or opportunistic attacks. Additionally, the absence of known public exploits currently provides a window for proactive mitigation, but also means attackers may develop exploits rapidly once the vulnerability is widely known. The impact extends beyond individual organizations to their customers and partners, potentially affecting supply chain security and trust.

1. Immediately audit and verify the access control configurations of the Everest Backup plugin to ensure that only authorized users can perform backup operations. 2. Restrict access to backup management interfaces by implementing network-level controls such as IP whitelisting or VPN access to limit exposure. 3. Monitor logs and backup operation activities for unusual or unauthorized actions that could indicate exploitation attempts. 4. Apply vendor patches or updates as soon as they become available; if no patch exists, consider temporarily disabling the plugin or replacing it with a more secure alternative. 5. Implement multi-factor authentication (MFA) for administrative accounts managing backups to add an additional security layer. 6. Regularly back up data using multiple methods and store backups securely offline or in segregated environments to mitigate risks from compromised backup plugins. 7. Educate IT and security teams about the vulnerability and ensure incident response plans include scenarios involving backup system compromise. 8. Engage with the vendor or community forums to track updates and share threat intelligence related to this vulnerability.
