CVE-2025-68645Known exploitationNetwork attack vector

Unauthenticated file inclusion via unrestricted RestFilter dispatch

Published Dec 22, 2025 · Updated Dec 22, 2025

Local file inclusion in Zimbra Collaboration 10.0 and 10.1 allows remote attackers to include WebRoot files through /h/rest requests. The RestFilter servlet accepts user-controlled request parameters and uses them to steer internal dispatching without restricting targets to an allowlist. No authentication is required, and reachability depends on the Classic UI exposing the endpoint; the disclosed file boundary is WebRoot.
