| CVE-2026-61908 | 2 Cyrus, Cyrusimap | 2 Imap, Cyrus Imap | 2026-09-16 | 3.1 Low |
| An issue was discovered in Cyrus IMAP before 3.12.4. A JMAP email-header blob ID can reference an out-of-bounds index. An authenticated user could attempt to download a crafted JMAP blob ID of the form H<emailid>-<index>, which could read past the end of the internal blob_headers array during download, exposing adjacent heap memory. | ||||
| CVE-2026-61909 | 2 Cyrus, Cyrusimap | 2 Imap, Cyrus Imap | 2026-09-16 | 3.5 Low |
| An issue was discovered in Cyrus IMAP before 3.12.4. CalDAV/CardDAV multiget bypasses a per-href ACL. An authenticated DAV user with some shared access to another user's calendar or address book could read even unshared events or contacts by including the target hrefs in a calendar-multiget or addressbook-multiget REPORT. | ||||
| CVE-2026-61910 | 2 Cyrus, Cyrusimap | 2 Imap, Cyrus Imap | 2026-09-16 | 3.5 Low |
| 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-2026-61911 | 2 Cyrus, Cyrusimap | 2 Imap, Cyrus Imap | 2026-09-16 | 4.3 Medium |
| An issue was discovered in Cyrus IMAP before 3.12.4. There is a Sieve mailbox existence oracle. An authenticated user could install a Sieve script that probed whether another user's private mailbox existed, or read the value of shared mailbox annotations, by observing which fileinto branch fired during LMTP delivery. | ||||
| CVE-2026-61915 | 2 Cyrus, Cyrusimap | 2 Imap, Cyrus Imap | 2026-09-16 | 4.2 Medium |
| An issue was discovered in Cyrus IMAP before 3.12.4. There is a VPATCH BYPARAM double-free. An authenticated calendar user could crash a Cyrus CalDAV worker with a PATCH containing PATCH-ACTION="BYPARAM@..." against a resource with two or more properties of the matched kind. The memory holding the selector would be freed once on each iteration over the properties. | ||||
| CVE-2005-0546 | 2 Cyrus, Redhat | 2 Imapd, Enterprise Linux | 2026-04-16 | N/A |
| Multiple buffer overflows in Cyrus IMAPd before 2.2.11 may allow attackers to execute arbitrary code via (1) an off-by-one error in the imapd annotate extension, (2) an off-by-one error in "cached header handling," (3) a stack-based buffer overflow in fetchnews, or (4) a stack-based buffer overflow in imapd. | ||||
| CVE-2006-2502 | 1 Cyrus | 1 Imapd | 2026-04-16 | N/A |
| Stack-based buffer overflow in pop3d in Cyrus IMAPD (cyrus-imapd) 2.3.2, when the popsubfolders option is enabled, allows remote attackers to execute arbitrary code via a long USER command. | ||||
| CVE-2017-14230 | 1 Cyrus | 1 Imap | 2025-04-20 | N/A |
| In the mboxlist_do_find function in imap/mboxlist.c in Cyrus IMAP before 3.0.4, an off-by-one error in prefix calculation for the LIST command caused use of uninitialized memory, which might allow remote attackers to obtain sensitive information or cause a denial of service (daemon crash) via a 'LIST "" "Other Users"' command. | ||||
| CVE-2015-8076 | 2 Cyrus, Opensuse | 3 Imap, Leap, Opensuse | 2025-04-12 | N/A |
| The index_urlfetch function in index.c in Cyrus IMAP 2.3.x before 2.3.19, 2.4.x before 2.4.18, 2.5.x before 2.5.4 allows remote attackers to obtain sensitive information or possibly have unspecified other impact via vectors related to the urlfetch range, which triggers an out-of-bounds heap read. | ||||
| CVE-2015-8077 | 2 Cyrus, Opensuse | 3 Imap, Leap, Opensuse | 2025-04-12 | N/A |
| Integer overflow in the index_urlfetch function in imap/index.c in Cyrus IMAP 2.3.19, 2.4.18, and 2.5.6 allows remote attackers to have unspecified impact via vectors related to urlfetch range checks and the start_octet variable. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8076. | ||||
| CVE-2015-8078 | 2 Cyrus, Opensuse | 3 Imap, Leap, Opensuse | 2025-04-12 | N/A |
| Integer overflow in the index_urlfetch function in imap/index.c in Cyrus IMAP 2.3.19, 2.4.18, and 2.5.6 allows remote attackers to have unspecified impact via vectors related to urlfetch range checks and the section_offset variable. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8076. | ||||
| CVE-2011-3372 | 2 Cyrus, Redhat | 2 Imapd, Enterprise Linux | 2025-04-11 | N/A |
| imap/nntpd.c in the NNTP server (nntpd) for Cyrus IMAPd 2.4.x before 2.4.12 allows remote attackers to bypass authentication by sending an AUTHINFO USER command without sending an additional AUTHINFO PASS command. | ||||
| CVE-2021-33582 | 4 Cyrus, Debian, Fedoraproject and 1 more | 5 Imap, Debian Linux, Fedora and 2 more | 2024-11-21 | 7.5 High |
| Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16. | ||||
| CVE-2021-32056 | 2 Cyrus, Fedoraproject | 2 Imap, Fedora | 2024-11-21 | 4.3 Medium |
| Cyrus IMAP before 3.2.7, and 3.3.x and 3.4.x before 3.4.1, allows remote authenticated users to bypass intended access restrictions on server annotations and consequently cause replication to stall. | ||||
| CVE-2019-19783 | 5 Canonical, Cyrus, Debian and 2 more | 5 Ubuntu Linux, Imap, Debian Linux and 2 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Cyrus IMAP before 2.5.15, 3.0.x before 3.0.13, and 3.1.x through 3.1.8. If sieve script uploading is allowed (3.x) or certain non-default sieve options are enabled (2.x), a user with a mail account on the service can use a sieve script containing a fileinto directive to create any mailbox with administrator privileges, because of folder mishandling in autosieve_createfolder() in imap/lmtp_sieve.c. | ||||
| CVE-2019-18928 | 4 Cyrus, Debian, Fedoraproject and 1 more | 4 Imap, Debian Linux, Fedora and 1 more | 2024-11-21 | 9.8 Critical |
| Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection. | ||||
| CVE-2019-11356 | 5 Canonical, Cyrus, Debian and 2 more | 8 Ubuntu Linux, Imap, Debian Linux and 5 more | 2024-11-21 | 9.8 Critical |
| The CalDAV feature in httpd in Cyrus IMAP 2.5.x through 2.5.12 and 3.0.x through 3.0.9 allows remote attackers to execute arbitrary code via a crafted HTTP PUT operation for an event with a long iCalendar property name. | ||||
