CVE-2026-3324Network attack vector

Unauthorized data access via misconfigured API filters

Published Apr 16, 2026 · Updated Apr 16, 2026

Authentication bypass in Zoho Corporation ManageEngine Log360 13000 through 13013 allows remote attackers to access data via exposed V1 APIs. Improper filter configuration on those API routes omits authorization checks that should reject unauthenticated requests. An exposed V1 API is required; successful requests disclose protected data and permit restricted operations, with no reported service interruption.
