CVE-2026-105820

5.4 medium SSVC exploitation: none Awaiting Analysis
NVD · CVE.org

Vault's ACL policy cache allowed namespace traversal when policy names contained path traversal constructs. This may allow a token assigned specially crafted policy names to use the capabilities of policies defined in other namespaces, including the root namespace. This vulnerability (CVE-2026-105820) is fixed in Vault Enterprise 2.1.2, 1.21.12, 1.20.17, and 1.19.23. Vault Community Edition does not support namespaces, and is not affected.
