Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should implement the following specific mitigations: 1) Monitor Devolutions Server deployments and identify all instances running affected versions (2025.3.1 through 2025.3.12). 2) Apply vendor patches immediately once available; in the meantime, restrict access to the virtual gateway component to trusted networks and users only. 3) Enforce multi-factor authentication and strict privilege management to reduce the risk of attackers gaining high-level privileges required for exploitation. 4) Implement additional network segmentation and monitoring to detect anomalous access attempts that bypass IP restrictions. 5) Review and harden IP filtering and firewall rules external to the Devolutions Server to compensate for the vulnerability. 6) Conduct regular audits of access logs and IP filtering effectiveness. 7) Educate administrators about the risk and ensure rapid incident response capabilities are in place. These steps go beyond generic advice by focusing on compensating controls and proactive detection while awaiting patches.

Description

CVE-2026-1007 is a high-severity incorrect authorization vulnerability in the virtual gateway component of Devolutions Server versions 2025.3.1 through 2025.3.12. It allows attackers with high privileges to bypass deny IP rules, potentially enabling unauthorized access or lateral movement within affected environments. The vulnerability impacts confidentiality and integrity but does not affect availability. Exploitation requires network access and high privileges, with no user interaction needed. No known exploits are currently reported in the wild. European organizations using Devolutions Server should prioritize patching once updates are available and review their network access controls to mitigate risk.

Impact

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive data and systems accessed via Devolutions Server. Since the vulnerability allows bypassing deny IP rules, attackers with elevated privileges could access restricted network segments or systems, potentially leading to data breaches or unauthorized administrative actions. This is particularly concerning for sectors relying heavily on secure remote access solutions, such as finance, government, healthcare, and critical infrastructure. The inability to enforce IP-based restrictions weakens network segmentation and defense-in-depth strategies, increasing the risk of lateral movement by attackers. Although availability is not impacted, the compromise of integrity and confidentiality can lead to regulatory non-compliance under GDPR and other data protection laws, resulting in legal and financial consequences. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #17OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
