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.

CVE-2026-115786A mailbox quota-accounting vulnerability in Zimbra Collaboration Suite (ZCS) allows an authenticated user to consume another user’s mailbox quota by repeatedly sharing and... Executive summary The advisory describes a mailbox quota accounting flaw in Zimbra Collaboration Suite (ZCS) that lets an authenticated user consume another user's mailbox quota by repeatedly sharing items. The text also lists a long set of Zimbra fixes, many with unscored issues, and the advisory does not state a severity rating for the quota flaw. The vendor recommends updating Zimbra with yum or apt to the latest release. Technical summary The quota flaw is an accounting weakness: an authenticated user can repeatedly share and unshare content to consume another user's mailbox quota. The advisory does not state a CVSS score, a fixed version for this specific CVE, a workaround, or detection guidance for it. The listed fixes span many classes, including stored and reflected XSS, LFI, SSRF, CSRF, XXE, authorization bypass, and command injection, with fix releases such as 10.1.21, 10.1.20, and 10.1.17, and most CVSS entries marked TBD. The advisory text is truncated, so the complete list and the fix release for CVE-2026-115786 cannot be confirmed from this text. Affected version ranges for the quota flaw, exploitation status, and vendor-published detection indicators are not stated. Summaries are generated by AI from the linked advisory text.

CVE-2026-115377Incus before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0 contains an arbitrary file write vulnerability that allows malicious migration sources to write host files by... Executive summary A flaw in Incus, a system container and virtual machine manager, lets a malicious migration source or a client allowed to create instances write arbitrary files to the host as root, which can lead to full host compromise. The advisory rates it Critical with a CVSS 3.1 base score of 9.9. The fixed releases named are Incus 6.0.7, 7.0.2, and 7.5.0, depending on the branch. Technical summary The weakness is CWE-59, improper link resolution before file access, where symlinks in a migration stream are followed when Incus replays the stream with rsync or btrfs receive. Exploitation requires network-reachable access as a client allowed to create instances or custom volumes in a project, or a malicious source server the target copies or moves from, with low privileges and no user interaction. The advisory states that releases before 7.3.0 are additionally affected by a rootfs symlink surviving the transfer, which can allow host files to be read. Affected versions are listed as before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0, and the GitHub package entry lists patched versions as 7.5.0 or later. The advisory does not state workarounds beyond restricting instance creation and migration to trusted clients and servers, and it does not state detection guidance or whether the flaw is exploited in the wild. Optimized ZFS transfers are stated to be unaffected. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
