What is CVE-2026-93335?

In Vault Community Edition and Vault Enterprise, an issue was identified wherein explicit ACL policy deny rules may not be properly applied to request paths differing only by a trailing slash. This flaw enables an authenticated user with broad delete permissions on configuration paths to potentially disable critical components such as secrets engines, authentication methods, or audit devices, circumventing specific deny regulations. This vulnerability highlights the necessity for stringent access control measures and is rectified in versions 2.2.2 and subsequent updates.

Affected Version(s)

Vault 64 bit 0.2.0 < 2.2.2

Vault Enterprise 64 bit 0.2.0 < 2.2.2
