AI Analysis
Technical Summary
This vulnerability (CVE-2026-3605) involves an authentication bypass related to policy glob patterns in HashiCorp Vault's kvv2 secret engine paths.

Potential Impact
An attacker with authenticated access and a policy containing a glob pattern can delete secrets they should not have permission to delete, causing denial-of-service. There is no impact on confidentiality since secret data cannot be read by unauthorized users, and no cross-namespace secret deletion is possible.
