CVE-2025-67985 identifies an authorization bypass vulnerability in the Barn2 Plugins Document Library Lite WordPress plugin, specifically affecting versions up to 1.1.7. The vulnerability arises from incorrectly configured access control mechanisms that rely on a user-controlled key parameter. Attackers can manipulate this key to bypass authorization checks, enabling them to perform unauthorized actions that compromise the integrity of documents or metadata within the document library. The vulnerability does not impact confidentiality or availability, as it does not expose sensitive data or cause denial of service. The CVSS 3.1 score of 5.3 reflects a medium severity, with an attack vector of network (remote exploitation), low attack complexity, no privileges required, and no user interaction needed. This means an unauthenticated attacker can exploit the vulnerability remotely without any user involvement. No known exploits have been reported in the wild, and no official patches or updates have been linked at the time of publication. The vulnerability affects organizations using the Document Library Lite plugin, commonly deployed in WordPress environments to manage and display documents. Exploitation could lead to unauthorized modifications or manipulations of document data, potentially undermining data integrity and trustworthiness of document repositories.

For European organizations, the primary impact of CVE-2025-67985 is the potential unauthorized modification of document data within WordPress sites using the affected plugin. This could disrupt business processes reliant on accurate document management, lead to misinformation, or damage organizational reputation. Although confidentiality and availability are not directly impacted, integrity violations can have significant operational consequences, especially in regulated industries such as finance, healthcare, or legal sectors where document accuracy is critical. The ease of remote exploitation without authentication increases the risk profile, particularly for publicly accessible websites. Organizations with extensive document management needs or those using Barn2 Plugins Document Library Lite as part of their content management strategy should be vigilant. The lack of known exploits in the wild suggests limited immediate threat, but the vulnerability remains a medium risk until patched. Attackers could leverage this flaw to alter document metadata or content, potentially facilitating further attacks or fraud.

1. Immediately review and restrict access permissions for the Document Library Lite plugin to trusted administrators only. 2. Implement strict input validation and sanitization for any user-controllable keys or parameters related to document access. 3. Monitor web server and application logs for unusual or unauthorized access patterns targeting the document library endpoints. 4. Where possible, disable or remove the Document Library Lite plugin if it is not essential to reduce the attack surface. 5. Stay informed on vendor updates and apply patches promptly once available. 6. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests attempting to manipulate authorization keys. 7. Conduct regular security audits of WordPress plugins and configurations to ensure compliance with best practices. 8. Educate site administrators about the risks of using outdated or vulnerable plugins and encourage timely updates.
