CVE-2026-105816

Summary

Vault fails to verify that plugin catalog entries reference binaries within the configured plugin directory, allowing a privileged operator with snapshot restoration access to potentially execute arbitrary code on the Vault host through a Shamir seal restore operation.

Exploitability

Exploitation requires a privileged operator with access to restore Integrated Storage (Raft) snapshots and an external plugin directory configuration, making it moderately difficult but possible for attackers who can gain operator privileges.

Blast radius

If exploited, this vulnerability could allow an attacker to execute arbitrary code on the Vault host, potentially leading to full compromise of the vault's secrets and access to all systems that trust Vault for authentication or secrets management.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Vault Community Edition 2.1.2 or Vault Enterprise 2.1.2, 1.21.12, 1.20.17, or 1.19.23 immediately.
