CVE-2025-62782Public exploitNetwork attack vector

Item duplication via inconsistent Bundle right-click handling

Published Oct 27, 2025 · Updated Oct 27, 2025

Improper single-action enforcement in Phoenix616 InventoryGui 1.6.3-SNAPSHOT and earlier allows remote authenticated users to duplicate items. GuiStorageElement mishandles a Bundle right-click by placing the Bundle in the GUI while retaining it on the cursor with one fewer contained item. Exploitation requires a plugin that uses GuiStorageElement on a server with experimental Bundle items enabled, and repeated interactions multiply inventory items.
