SCA: security update for github.com/axllent/mailpit (GHSA-r553-m4fv-5v97)

medium Tenable Self-Hosted Container Security Plugin ID 446180

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Mailpit is an email testing tool and API for developers. From 1.30.0 until 1.30.5, Mailpit's
 internal/smtpd/smtpd.go readData() function calls bufio.Reader.ReadBytes before applying the
 len(data)+len(line) size check to the completed SMTP DATA line against Server.MaxSize. An unauthenticated
 SMTP client can send a single line larger than the configured MaxMessageSize, causing the full line to be
 allocated before Mailpit returns the 552 5.3.4 rejection. This post-fix gap remains after normal multi-
 line DATA accumulation was bounded, and concurrent oversized lines can create substantial memory pressure
 beyond the configured message-size cap. This issue is fixed in version 1.30.5. (CVE-2026-67447)

Solution

Update the github.com/axllent/mailpit library and its related packages to version 1.30.5 or later.
