CVE-2026-33419 (opens in a new tab)How to fix?
There is no fixed version for github.com/minio/minio/internal/config/identity/ldap.
Overview
Affected versions of this package are vulnerable to Brute Force via the AssumeRoleWithLDAPIdentity endpoint, which exposes distinguishable error messages and lacks rate limiting. An attacker can enumerate valid LDAP usernames and perform unlimited password guessing to obtain temporary credentials by sending repeated authentication attempts over the network.
Note:
This is only exploitable if LDAP authentication is enabled and accessible from untrusted networks.
This package (
minio/minio) has been renamed/succeeded byminio/aistoron Quay. The fix is available only in the new package starting from tagRELEASE.2026-03-17T21-25-16Z.
Workaround
This vulnerability can be mitigated by implementing network-level rate limiting using a reverse proxy or WAF, restricting access to the endpoint to trusted networks or IP ranges, and configuring LDAP account lockout policies on the LDAP server.
