10 security issues in bullseye high

There are 10 open security issues in bullseye.

9 important issues:

CVE-2026-47081: 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-2026-47082: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. The vacation "fcc" feature skips the destination-mailbox ACL. A user whose vacation Sieve script used :fcc (to save a copy of the sent message) could deliver vacation auto-reply copies into any mailbox the script could name, regardless of whether the script owner had insert permissions on the destination mailbox.
CVE-2026-47083: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an ESEARCH cross-user content oracle. By using the ESEARCH command, an authenticated IMAP user could enumerate folder names under any account they could name. Search would return UIDs of messages matching the search, creating a content oracle (without allowing arbitrary reads of the target's content).
CVE-2026-47084: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. The LOCALDELETE command bypassed ACL checks. An authenticated but non-admin user could invoke the admin-only LOCALDELETE IMAP command and delete mailboxes for which they had no permissions.
CVE-2026-47085: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH token forgery can occur via a missing mboxkey. If an attacker knew a folder name on the victim's account for which the victim had never issued an auth URL, they could forge a working URLAUTH token by computing an HMAC-SHA1 value with a predictable key, giving them read access to the mailbox. (URLAUTH is an obscure feature, meaning that the odds of any user actually being susceptible to this attack are very low. Perhaps no public clients use URLAUTH.)
CVE-2026-47086: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. GENURLAUTH-issued tokens can bypass ACLs. Any authenticated user could mint a URLAUTH token (via the GENURLAUTH command) for any mailbox they could name, even without read access on it. This would allow reading mail from mailboxes despite having no granted permissions.
CVE-2026-47087: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH does not honor revoked authorizer access. A URLAUTH URL minted while the authorizer had access continued to work after that access was revoked.
CVE-2026-47088: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is heap exposure in nested MIME comment parsing. An authenticated IMAP user could craft an email message containing an RFC 822 comment ending with a backslash. When parsing the message, the server would read past the message's end in memory, and read into the heap, returning the read content to the user.
CVE-2026-47089: An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. LISTRIGHTS os not limited to users with admin access. An authenticated user could call IMAP LISTRIGHTS against any mailbox they could name and learn what principals had what access to it. (This action should have been restricted to users with admin access on the target mailbox.)

1 ignored issue:

CVE-2024-34055: Cyrus IMAP before 3.8.3 and 3.10.x before 3.10.0-rc1 allows authenticated attackers to cause unbounded memory allocation by sending many LITERALs in a single command.
