Vulnerability Advisory : Vault vulnerable to ACL deny bypass via trailing slash with LOW Attack Complexity

Vault Community Edition and Vault Enterprise did not consistently apply explicit ACL policy deny rules to request paths that differ only by a trailing slash. This may allow an authenticated user who holds a broader delete permission on system configuration paths to disable a secrets engine, auth method, or audit device that a more specific deny rule was intended to protect. This vulnerability (CVE-2026-93335) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.25.
