Zimbra Collaboration Suite GraphQL Batched Authentication Bypasses Pre-Auth Rate Limiting
An authentication rate-limit bypass in Zimbra Collaboration Suite 10.1.0 through 10.1.21 allows unauthenticated attackers to make repeated password guesses through GraphQL without incrementing Zimbra’s source-IP failure counter.
