SCA: security update for github.com/knadh/listmonk (GHSA-jc7g-x28f-3v3h)

medium Tenable Self-Hosted Container Security Plugin ID 437093

Description

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

 - listmonk is a standalone, self-hosted, newsletter and mailing list manager. Starting in version 4.0.0 and
 prior to version 5.0.2, the `env` and `expandenv` template functions which is enabled by default in Sprig
 enables capturing of env variables on host. While this may not be a problem on single-user (super admin)
 installations, on multi-user installations, this allows non-super-admin users with campaign or template
 permissions to use the `{{ env }}` template expression to capture sensitive environment variables. Users
 should upgrade to v5.0.2 to mitigate the issue. (CVE-2025-49136)
