Linux Distros Unpatched Vulnerability : CVE-2026-47081

low Nessus Plugin ID 327548

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an XAPPLEPUSHSERVICE folder existence oracle and push hijack. An authenticated IMAP user could probe for the existence of arbitrary mailboxes on other users' accounts via the XAPPLEPUSHSERVICE command and then create Apple Push Notification Service notifications for new mail in those mailboxes to their own APNS device. This did not leak any data about the content of mailboxes. Instead, a mailbox has changed notice would be pushed when the mailbox modseq changed. (CVE-2026-47081)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
