CVE-2026-115786 is a mailbox quota-accounting vulnerability in Zimbra Collaboration Suite versions up to 10.1.20. An authenticated user can exploit this flaw by repeatedly sharing and revoking a document, causing the recipient's mailbox quota usage to increase incorrectly. This happens because revoking the share reverses folder counters but does not reverse the mailbox-wide quota charge, leading to quota consumption without visible records. On accounts with finite quotas, this can block incoming mail and other operations that increase mailbox size.
