UBUNTU-CVE-2026-82854

Nodemailer before 8.0.4 is vulnerable to SMTP command injection through the unsanitized envelope.size parameter. When an application passes a custom envelope object with a size property containing CRLF characters to sendMail, the value is concatenated into the SMTP MAIL FROM command as SIZE=...

UBUNTU-CVE-2026-82661

Nodemailer before 8.0.9 fails to sanitize carriage return and line feed characters in list comment fields, allowing attackers to inject arbitrary message headers. An attacker with control over list..comment parameters can inject CRLF sequences to create additional headers in generated RFC822...

net/mail: golang: Go net/mail: Denial of Service via crafted email inputs

A flaw was found in the net/mail package of the Go programming language. An attacker could provide specially crafted inputs to the ParseAddress, ParseAddressList, or ParseDate functions. This could lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service DoS for...

net/mail: golang: net/mail: Denial of Service via pathological email address parsing

A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...

Linux Distros Unpatched Vulnerability : CVE-2026-42007

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An attacker that has valid credentials can use a Sieve script with the editheader extension to trigger a use-after-free in the mail editing code, and to write...

Linux Distros Unpatched Vulnerability : CVE-2026-33606

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administrator later runs dsync with the stream protoco...

Linux Distros Unpatched Vulnerability : CVE-2026-40014

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message...

Linux Distros Unpatched Vulnerability : CVE-2026-52681

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Sieve CPU resource usage is tracked in the compiled script, so an attacker that has valid credentials can reset the accounting by repeatedly changing the active...

Linux Distros Unpatched Vulnerability : CVE-2026-27852

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An attacker that can send mail to a user can craft a message whose headers contain a very large number of email addresses or MIME parameters, which causes...

ALPINE-CVE-2026-42007

An attacker that has valid credentials can use a Sieve script with the editheader extension to trigger a use-after-free in the mail editing code, and to write memory contents beyond the intended buffer into the delivered mail. This causes memory leak and opportunity to do memory corruption during...

CVE-2026-40014

An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message. When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for IMAP. Monitor...

CVE-2026-33263

When mailmaxuseripconnections is set default 10 and reached, submission-login can crash with epoll panic caused by file descriptor handling issues. If running in high-security mode default for community releases, only the new submission connection gets terminated. If running in high-performance...

ALPINE-CVE-2026-33606

Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administrator later runs dsync with the stream protocol, for example during a migration. Injected commands can modify mailbox state on the destination during migration or replication, includi...

CVE-2026-27852

An attacker that can send mail to a user can craft a message whose headers contain a very large number of email addresses or MIME parameters, which causes excessive memory usage when the message is later parsed. The message is still delivered, but reading it over IMAP can exhaust the memory limit...
