Echo: lodash: security update to 4.18.0

critical Tenable Self-Hosted Container Security Plugin ID 460996

Description

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

- The fix for CVE-2021-23337 added validation for the variable option in _.template but did not apply the
same validation to options.imports key names, and both paths flow into the same Function() constructor
sink. When an application passes untrusted input as options.imports key names, an attacker can inject
default-parameter expressions that execute arbitrary code at template compilation time. Additionally,
_.template uses assignInWith to merge imports, which enumerates inherited properties via for..in, so if
Object.prototype has been polluted by another vector the polluted keys are copied into the imports object
and passed to Function(). The issue is fixed in 4.18.1 for lodash, lodash-es, lodash-amd, and
lodash.template. As a workaround, do not pass untrusted input as key names in options.imports; use only
developer-controlled, static key names. (CVE-2026-4800)

Solution

Update the lodash library and its related packages to version 4.18.0 or later.
