CVE-2025-49240 is a Missing Authorization vulnerability (CWE-862) identified in the nK DocsPress product, affecting versions up to 2.5.2. This vulnerability arises from incorrectly configured access control security levels, allowing users with some level of privileges (as indicated by the CVSS vector requiring low privileges) to access resources or perform actions they should not be authorized to. Specifically, the vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The impact is limited to confidentiality loss (C:L) without affecting integrity or availability. This suggests that an attacker with some level of authenticated access could view or access sensitive information that should be restricted, but cannot modify or disrupt the system. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability was published recently in June 2025, indicating that organizations using DocsPress should be vigilant and monitor for forthcoming patches or mitigations.

For European organizations, the confidentiality breach posed by this vulnerability could lead to unauthorized disclosure of sensitive documents or internal information managed via DocsPress. This could have regulatory implications, especially under GDPR, where unauthorized access to personal or confidential data can result in significant fines and reputational damage. While the vulnerability does not allow data modification or service disruption, the exposure of confidential information could facilitate further attacks such as social engineering or targeted phishing. Organizations in sectors handling sensitive data—such as finance, healthcare, legal, and government—may face heightened risks. Additionally, the medium severity rating suggests that while the risk is not critical, it should not be ignored, especially in environments where DocsPress is used to manage sensitive documentation.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Conduct an immediate audit of user roles and permissions within DocsPress to ensure the principle of least privilege is enforced, removing unnecessary access rights. 2) Implement network segmentation and restrict access to DocsPress instances to trusted internal networks or VPNs to reduce exposure to remote exploitation. 3) Enable and monitor detailed access logs to detect any unauthorized access attempts or unusual user behavior. 4) If possible, deploy Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting DocsPress endpoints. 5) Prepare for rapid patch deployment by establishing a vulnerability management process that includes timely application of updates once available. 6) Educate users about the risks of unauthorized data access and encourage reporting of suspicious activity. These measures go beyond generic advice by focusing on access control auditing, network restrictions, and proactive monitoring tailored to the nature of this vulnerability.
