SCA: security update for immutable (GHSA-xvcm-6775-5m9r)

high Tenable Cloud Security Plugin ID 445101

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, Immutable.Map
 and Immutable.Set keep keys that share the same 32-bit hash in a HashCollisionNode collision bucket that
 is scanned linearly, allowing an attacker who controls keys inserted into a Map, such as through
 Immutable.Map(obj), Immutable.fromJS(obj), state.merge(userObject), or mergeDeep, to craft many colliding
 keys and degrade insertion and lookup to consume disproportionate CPU. This issue is fixed in versions
 4.3.9 and 5.1.8. (CVE-2026-59880)

Solution

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