AI Threat Summary

CVE-2026-109592 is a moderate vulnerability with a CVSS score of 4.3 affecting the target software. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

The OpenStation: Desktop Windows, Dock & Virtual Desktops for WP Admin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.16. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary other users' placement rows (position, sort order, parent folder, and meta) and read serialized metadata — including title, permalink, and post status — of the entities those orphaned placements reference. Exploitation requires at least one orphaned placement to exist — a state produced naturally by the plugin's own trash cascade, which marks a parent folder as trashed while leaving child placements' parent_id intact — and the attacker must first self-enable OpenStation via the save-openstation AJAX endpoint, which requires only the 'read' capability held by every default WordPress role. This was also independently found by the OpenStation team.
