CVE-2025-13357 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Vault’s Terraform Provider incorrectly set the default deny_null_bind parameter for the LDAP auth method to false by default, potentially resulting in an insecure configuration. If the underlying LDAP server allowed anonymous or unauthenticated binds, this could result in authentication bypass. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
