Critical Zimbra flaw enables code execution via crafted emails
A critical vulnerability in Zimbra could allow specially crafted emails to execute malicious code within a user’s active webmail session. The issue affects client-side interaction with email content, turning message delivery itself into the attack vector.
Operationally, this reduces the barrier to compromise for any organization relying on Zimbra webmail. If exploited, a single inbound message could trigger session-level code execution, making mailbox access a direct path for credential abuse, persistence, or follow-on activity inside enterprise communications workflows.
