SCA: security update for github.com/axllent/mailpit (GHSA-8r62-w5wh-fc5m)

medium Tenable Cloud Security Plugin ID 446204

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 1.29.0 until 1.30.6, Mailpit's
 server/server.go origin middleware checks the raw RequestURI for the /api/ prefix while Go's ServeMux
 routes using the percent-decoded URL path, and server/websockets/client.go configures
 websocket.Upgrader.CheckOrigin to return true. A malicious website can request /%61pi/events, skip
 corsOriginAccessControl(), reach the /api/events WebSocket handler, and receive live message IDs, Message-
 Id values, sender and recipient fields, subjects, tags, and body snippets from an unauthenticated default
 Mailpit instance after the user visits the site. This is a regression of the earlier WebSocket origin
 protection and does not affect deployments protected by --ui-auth-file. This issue is fixed in version
 1.30.6. (CVE-2026-67448)

Solution

Update the github.com/axllent/mailpit library and its related packages to version 1.30.6 or later.
