SCA: security update for immutable (GHSA-v56q-mh7h-f735)

high Tenable Self-Hosted Container Security Plugin ID 445102

Description

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

 - Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, List#set,
 List#setSize, List#setIn, List#updateIn, and the functional set, setIn, and updateIn mishandle an index or
 size in the range 2 ** 30 to 2 ** 31 in setListBounds in src/List.js, causing an empty List to enter an
 uncatchable infinite loop, a populated List to allocate without bound until process abort, or setSize to
 silently wrap large values. This issue is fixed in versions 4.3.9 and 5.1.8. (CVE-2026-59879)

Solution

Update the immutable library and its related packages to version 4.3.9 or later.
