CVE-2026-93627An organizer authentication vulnerability in the email calendar processing of Zimbra Collaboration Suite (ZCS) allows an unauthenticated sender to cancel or modify an existing... Executive summary The advisory is a Zimbra Collaboration Suite security advisory listing many fixed vulnerabilities, including cross-site scripting, authorization flaws, file inclusion, and command injection issues across multiple releases. The advisory does not describe one single severity level for the set, and most entries have no CVSS score stated. The vendor recommends updating Zimbra to the latest release or patch using yum or apt update. Technical summary The advisory covers a large batch of fixes spanning cross-site scripting, CSRF, SSRF, local and remote file inclusion, XXE, LDAP injection, authorization bypasses, and a command injection in the SNMP monitoring component, among others. Attack vectors and preconditions vary by entry; some require authentication and others are unauthenticated, as noted in individual entries. Fixed versions are listed as written in the table, such as 10.1.21, 10.1.20, 10.1.17, 10.1.16, and older patch levels like 9.0.0 Patch 46, 10.0.15, and 10.1.9. Most entries have CVSS scores listed as TBD, and some have none. The advisory does not state workarounds for most entries, and it gives no detection guidance beyond upgrading. Exploitation in the wild is not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
