Title
Vault Vulnerable to Privilege Escalation via Slash Injection in Templated Policy Paths
Summary
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.
