CVE-2026-50056 is a local privilege escalation vulnerability in the zmmailboxdmgr launcher of Zimbra Collaboration Suite (ZCS). It allows the Unix zimbra account to execute arbitrary commands as root by exploiting insufficient restriction of JVM arguments in a passwordless sudo interface. The attack involves postponing Jetty's privilege drop and forcing heap exhaustion during startup to execute commands with root privileges. This requires local command execution as the zimbra user on a mailbox server and interrupts mailboxd during restart. Versions up to and including 10.1.21 are affected.
