What is CVE-2025-6013?

The LDAP authentication method in Vault and Vault Enterprise may allow for an MFA enforcement bypass when the 'username_as_alias' feature is enabled. This issue arises particularly when user accounts contain multiple common names (CNs) that only differ by leading or trailing whitespace. As a result, users may not be prompted for multi-factor authentication as expected, potentially exposing sensitive resources. The issue has been addressed in recent updates to the respective versions of Vault.

Affected Version(s)

Vault 64 bit 1.10.0 < 1.20.2

Vault Enterprise 64 bit 1.10.0 < 1.20.2
