Description

Vault is vulnerable to a denial-of-service condition where an unauthenticated attacker can repeatedly initiate or cancel root token generation or rekey operations, occupying the single in-progress operation slot. This prevents legitimate operators from completing these workflows. This vulnerability, CVE-2026-5807, is fixed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0.
