Description
InventoryGui is a library for creating chest GUIs for Bukkit/Spigot plugins. Versions before 1.6.5 contain a vulnerability where any plugin using a GUI with the GuiStorageElement and allows taking out items out of that element can allow item duplication when the experimental Bundle item feature is enabled on the server. The vulnerability is resolved in version 1.6.5.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.themoep:inventorygui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update de.themoep:inventorygui to 1.6.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-62784 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-62784 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-62784. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
