AI Analysis
Technical Summary
This vulnerability (CWE-288) in HashiCorp Vault involves an authenticated user exploiting a policy with a glob pattern on a kvv2 path to delete secrets beyond their authorized scope, resulting in denial-of-service. It does not allow unauthorized reading of secrets or cross-namespace deletion. The flaw is addressed in multiple fixed versions of Vault Community and Enterprise editions.
Potential Impact
An attacker with authenticated access and a policy containing a glob can delete secrets they should not be able to, causing denial-of-service by removing critical secrets. However, the vulnerability does not allow unauthorized reading of secret data or deletion across namespaces, limiting the scope of impact to denial-of-service within the affected namespace.
Mitigation Recommendations
This vulnerability is fixed in Vault Community Edition 2.0.0 and Vault Enterprise versions 2.0.0, 1.21.5, 1.20.10, and 1.19.16. Users should upgrade to one of these versions or later to remediate the issue. Patch status is confirmed by the vendor advisory. No additional mitigations are indicated.
