CVE-2026-1007 identifies an incorrect authorization vulnerability in the virtual gateway component of Devolutions Server, specifically affecting versions from 2025.3.1 through 2025.3.12. The vulnerability allows attackers to bypass deny IP rules, which are typically used to restrict access from unauthorized IP addresses. This bypass occurs due to improper enforcement of authorization checks within the virtual gateway, categorized under CWE-863 (Incorrect Authorization). The virtual gateway is a critical component that manages network access and routing for remote connections. By circumventing deny IP rules, an attacker can gain unauthorized access to the server or connected resources, potentially leading to unauthorized data access or lateral movement within a network. No CVSS score has been assigned yet, and no known exploits have been reported in the wild as of the publication date. However, the vulnerability's nature suggests that exploitation does not require authentication or user interaction, increasing the risk. The lack of patch links indicates that a fix may still be pending or in development. Organizations using affected versions should be aware of the risk and monitor for updates from Devolutions. The vulnerability poses a significant threat to environments relying on IP-based access controls for security, as it undermines a fundamental layer of network defense.

For European organizations, the impact of CVE-2026-1007 can be substantial, especially for those relying on Devolutions Server for remote access and credential management. Bypassing deny IP rules can allow attackers to connect from unauthorized locations, increasing the risk of unauthorized data access, credential theft, or lateral movement within corporate networks. This can compromise confidentiality and integrity of sensitive information and potentially disrupt availability if attackers leverage access for further attacks. Critical sectors such as finance, healthcare, government, and energy that depend on secure remote access solutions are particularly vulnerable. The vulnerability undermines network perimeter defenses, which are often a key component of European organizations' cybersecurity strategies. Additionally, the absence of a patch at the time of disclosure means organizations must rely on compensating controls, increasing operational complexity and risk exposure. The potential for exploitation without authentication or user interaction further elevates the threat level.

1. Monitor official Devolutions channels closely for patch releases addressing CVE-2026-1007 and apply updates promptly once available. 2. Implement network-level access controls such as VPNs with multi-factor authentication and IP whitelisting to supplement or replace reliance on deny IP rules within the server. 3. Restrict management interfaces of Devolutions Server to trusted networks and enforce strict firewall rules to limit exposure. 4. Conduct regular audits of access logs and network traffic to detect anomalous connections that may indicate bypass attempts. 5. Employ intrusion detection and prevention systems (IDS/IPS) to identify and block suspicious activities targeting the virtual gateway component. 6. Consider segmenting critical assets and limiting the scope of access granted through Devolutions Server to minimize potential damage from exploitation. 7. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling if exploitation is suspected. 8. Use network anomaly detection tools to identify unusual IP addresses or connection patterns that bypass deny IP rules.
