Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 IMAP before 3.12.4. Mailbox/set let a sharee change a special-use role on     shared mailboxes. An authenticated user with maySetKeywords on another user's mailbox could change that     mailbox's specialuse annotation. This could allow the sharee to change the shared mailbox to perform the     archived, snoozed, or other role, which might cause mail mail to be written to the shared mailbox, sharing     more content than intended. (This is likely to be an unusual situation, made more unusual because if the     target already has an non-shared mailbox with that role, role duplication suppression will prevent the     update.) (CVE-2026-61910)

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

The remote Fedora 45 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-3bf3e31ef4 advisory.
