SCA: security update for github.com/knadh/listmonk (GHSA-h5j9-cvrw-v5qh)

high Tenable Cloud Security Plugin ID 439602

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. From version 4.1.0 to before
 version 6.1.0, a session management vulnerability allows previously issued authenticated sessions to
 remain valid after sensitive account security changes, specifically password reset and password change. As
 a result, an attacker who has already obtained a valid session cookie can retain access to the account
 even after the victim changes or resets their password. This weakens account recovery and session security
 guarantees. This issue has been patched in version 6.1.0. (CVE-2026-34828)

Solution

Update the github.com/knadh/listmonk library and its related packages to version 1.1.1-0.20260329113754-1b5e8d38c778 or later.
