## Overview

Vault and Vault Enterprise did not consistently verify that stored plugin catalog entries reference binaries within the configured plugin directory. When Vault uses Shamir seals and has an external plugin directory configured, a privileged operator able to restore an Integrated Storage (Raft) snapshot may be able to execute arbitrary code on the Vault host. This vulnerability (CVE-2026-105816) is fixed in Vault Community Edition 2.1.2, and Vault Enterprise 2.1.2, 1.21.12, 1.20.17, and 1.19.23.
