SCA: security update for github.com/axllent/mailpit (GHSA-w4vj-r5pg-3722)

medium Tenable Cloud Security Plugin ID 442153

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 screenshot/print
 proxy (/proxy?data=…) maintains a package-level assets map[string]MessageAssets cache, but reads the map
 without holding assetsMutex while a long-running cleanup goroutine and (re-entrant) CSS-rewriting code
 path concurrently write to it under the lock. When the unsynchronized read coincides with a synchronized
 write, Go's runtime raises fatal error: concurrent map read and map write — a runtime.throw that is not
 recoverable by http.Server's handler-panic recover. The whole Mailpit process exits, taking the SMTP, POP3
 and HTTP listeners down with it. Version 1.30.0 contains a patch. (CVE-2026-45712)

Solution

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