SCA: security update for github.com/axllent/mailpit (GHSA-qx5x-85p8-vg4j)

medium Tenable Cloud Security Plugin ID 442156

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. Prior to version 1.30.0, the mailpit dump --http
 <base-url> <out-dir> sub-command downloads every message from a remote Mailpit instance and writes each
 one as <id>.eml inside the user-supplied output directory. The message ID field is taken verbatim from the
 JSON response of the remote server and concatenated into the output path with path.Join, which silently
 normalizes `..` segments. A malicious HTTP server impersonating Mailpit can therefore make mailpit dump
 write attacker-controlled bytes to any path the running user can write, fully outside the intended output
 directory. Version 1.30.0 contains a patch. (CVE-2026-45711)

Solution

Update the github.com/axllent/mailpit library and its related packages to version 1.30.0 or later.
