SCA: security update for gov.nsa.emissary:emissary (GHSA-6c37-7w4p-jg9v)

high Tenable Cloud Security Plugin ID 439998

Description

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

- Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, the Executrix utility class
constructed shell commands by concatenating configuration-derived values — including the PLACE_NAME
parameter — with insufficient sanitization. Only spaces were replaced with underscores, allowing shell
metacharacters (;, |, $, `, (, ), etc.) to pass through into /bin/sh -c command execution. This
vulnerability is fixed in 8.39.0. (CVE-2026-35581)

Solution

Update the gov.nsa.emissary:emissary library and its related packages to version 8.39.0 or later.
