SCA: security update for underscore (GHSA-qpx9-hpmf-5gmw)

high Tenable Cloud Security Plugin ID 438099

Description

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

 - Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual
 functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker
 could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input
 must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth
 limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten,
 the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure
 that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to
 _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path
 in which two distinct datastructures that were submitted by the same remote client are compared using
 _.isEqual. For example, if a client submits data that are stored in a database, and the same client can
 later submit another datastructure that is then compared to the data that were saved in the database
 previously, OR if a client submits a single request, but its data are parsed twice, creating two non-
 identical but equivalent datastructures that are then compared. Exceptions originating from the call to
 _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed
 in 1.13.8. (CVE-2026-27601)

Solution

Update the underscore library and its related packages to version 1.13.8 or later.
