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.
