Summary

HashiCorp Vault and Vault Enterprise from 0.0.1 before 2.1.2 are affected. ACL policy evaluation does not consistently check the canonical form of resource and policy names, which is improper handling of case sensitivity (CWE-178). An authenticated user with delegated permissions can bypass an explicit deny restriction to access a protected resource or assign a denied policy, which can lead to privilege escalation.

Description from the CNA

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.
