CVE-2026-5006

A vulnerability was identified in HashiCorp Vault and Vault Enterprise (“Vault”) such that an authenticated attacker may manipulate an identity value referenced by a templated policy path to gain unintended access to Vault paths. An attacker who can control the referenced identity value may include slash ({{/}}) characters that Vault interprets as additional path segments when rendering the policy. This vulnerability, CVE-2026-5006, was fixed in Vault Community Edition 2.0.4 and Vault Enterprise 2.0.4, 1.21.9, 1.20.14, and 1.19.20.
