CVE-2026-89322

Vault and Vault Enterprise did not consistently evaluate ACL policies against the canonical form of resource and policy names. This may allow an authenticated user with delegated permissions to bypass an explicit deny restriction and access a protected resource or assign a denied policy, potentially leading to privilege escalation. This vulnerability (CVE-2026-89322) 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.
