HIGH

HashiCorp Vault Terraform Provider < 5.5.0 - Insecure Default LDAP Authentication Configuration

Title source: llm

Description

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. This vulnerability, CVE-2025-13357, is fixed in Vault Terraform Provider v5.5.0.
