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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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 30 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.

AI-suggested

Users should monitor the vendor's advisory for updates. In the meantime, restricting user roles to prevent subscriber-level users from accessing the plugin or disabling the plugin if not required may reduce risk. Since exploitation requires enabling OpenStation via an AJAX endpoint accessible with minimal privileges, monitoring and restricting access to this endpoint could also help mitigate exploitation.

Description

The OpenStation: Desktop Windows, Dock & Virtual Desktops for WP Admin WordPress plugin contains an authorization bypass vulnerability in all versions up to and including 1.1.16. This flaw allows authenticated users with subscriber-level access or higher to modify other users' placement rows and read serialized metadata of referenced entities. Exploitation requires the presence of orphaned placements, a state created by the plugin's trash cascade mechanism, and the attacker must enable OpenStation via an AJAX endpoint accessible with minimal privileges.

Impact

The vulnerability allows unauthorized modification of other users' placement data and unauthorized reading of serialized metadata, potentially leading to information disclosure and integrity issues within the plugin's managed data. However, it does not allow privilege escalation or denial of service. The CVSS score of 4.3 reflects a medium severity impact with limited confidentiality and integrity impact and no availability impact.

Summary

CVE-2026-109592 describes an authorization bypass vulnerability in the OpenStation WordPress plugin (up to version 1.1.16). The plugin fails to properly verify user authorization for certain actions, enabling authenticated users with subscriber-level access or above to alter arbitrary users' placement rows (including position, sort order, parent folder, and metadata) and read serialized metadata such as title, permalink, and post status. Exploitation depends on the existence of orphaned placements, which occur naturally due to the plugin's trash cascade process that marks parent folders as trashed but leaves child placements' parent_id unchanged. Attackers must self-enable OpenStation through a save-openstation AJAX endpoint, which requires only the 'read' capability present in all default WordPress roles. The vulnerability was independently discovered by the OpenStation team.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
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.
