CVE-2025-68585 identifies a Missing Authorization vulnerability in the WP Document Revisions plugin developed by Ben Balter, affecting versions up to and including 3.7.2. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from accessing or modifying document revisions managed by the plugin. WP Document Revisions is a WordPress plugin used to manage document versioning and collaboration within WordPress sites. The missing authorization means that an attacker, without authentication or user interaction, could potentially exploit this flaw to gain unauthorized access to sensitive documents or alter document revisions, compromising data integrity and confidentiality. Although no known exploits are reported in the wild, the vulnerability is publicly disclosed and published with no CVSS score assigned yet. The issue stems from a fundamental security misconfiguration rather than a complex exploit technique, making it relatively straightforward to exploit if the plugin is present and active on a site. The vulnerability affects all installations running the vulnerable versions, which may be widespread given the popularity of WordPress and this plugin for document management. The lack of patch links suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps by administrators.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WP Document Revisions for internal document management and collaboration. Unauthorized access to document revisions can lead to data leakage of sensitive or confidential information, potentially violating GDPR and other data protection regulations. Integrity of documents can be compromised if attackers modify or delete revisions, disrupting business processes and trustworthiness of records. Availability impact is moderate but could occur if attackers manipulate document states or cause denial of service through repeated unauthorized access attempts. The vulnerability's ease of exploitation without authentication increases risk exposure. Organizations in sectors such as finance, healthcare, legal, and government, which handle sensitive documents, are particularly at risk. The reputational damage and regulatory penalties from data breaches could be severe. Additionally, the lack of known exploits in the wild currently provides a window for proactive defense but also means organizations should act swiftly to prevent future exploitation.

Immediate mitigation should focus on restricting access to the WP Document Revisions plugin by limiting its use to trusted users and roles only. Administrators should audit current user permissions and remove or limit access where unnecessary. Employ web application firewalls (WAFs) with custom rules to detect and block unauthorized attempts to access document revisions endpoints. Monitor logs for unusual access patterns related to document revisions. Until an official patch is released, consider disabling or uninstalling the plugin if feasible, or isolating it in a segmented environment with strict access controls. Regularly check for updates from the vendor and apply patches promptly once available. Implement strong authentication and authorization mechanisms at the WordPress level, including multi-factor authentication for admin users. Educate users about the risks of unauthorized document access and encourage reporting of suspicious activity. Finally, conduct penetration testing focused on access control weaknesses to identify and remediate similar issues proactively.
