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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 24 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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.

What to do

Upgrade Devolutions Server to 2025.3.15.

AI-suggested

To mitigate CVE-2026-1768, organizations should promptly upgrade Devolutions Server to version 2025.3.15 or later where the vulnerability is fixed. If immediate patching is not feasible, administrators should restrict access to the server to trusted networks and enforce strong authentication mechanisms to limit the pool of authenticated users. Implementing strict role-based access controls (RBAC) and regularly auditing user permissions can reduce the risk of privilege abuse. Monitoring logs for unusual access patterns or permission changes may help detect exploitation attempts. Additionally, isolating Devolutions Server from general user networks and employing network segmentation can limit exposure. Organizations should also consider temporary compensating controls such as disabling caching features if configurable, or applying custom access filters to prevent permission cache poisoning. Finally, educating users about credential security and promptly revoking access for compromised accounts will further reduce risk.

Description

A permission cache poisoning vulnerability in Devolutions Server allows authenticated users to bypass permissions to access entries.This issue affects Devolutions Server: before 2025.3.15.

Impact

The primary impact of CVE-2026-1768 is unauthorized disclosure of sensitive information managed by Devolutions Server. Since the product is used for managing privileged credentials and remote connections, unauthorized access to these entries can lead to further lateral movement, privilege escalation, and potential compromise of critical systems. Although the vulnerability does not directly affect data integrity or system availability, the confidentiality breach can have severe downstream consequences, including exposure of administrative credentials or secrets. Organizations relying on Devolutions Server for secure credential storage and access management face increased risk of insider threats or compromised user accounts being leveraged to bypass security controls. The medium severity rating suggests moderate urgency, but the sensitive nature of the data involved elevates the risk profile. The absence of known exploits reduces immediate threat but does not eliminate the risk of future exploitation. Enterprises in sectors such as finance, government, healthcare, and critical infrastructure that depend on Devolutions Server for secure access management are particularly vulnerable to targeted attacks exploiting this flaw.

CWE-863Incorrect Authorization (opens in a new tab)
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.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
