SCA: security update for ts-deepmerge (GHSA-87mf-gv2c-c62c)

medium Tenable Cloud Security Plugin ID 443743

Description

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

 - Versions of the package ts-deepmerge before 8.0.0 are vulnerable to Uncaught Exception due to the improper
 handling of built-in Object.prototype methods (such as toString, valueOf). When user-controlled input
 contains these keys with non-function values, the resulting merged object becomes broken — any string
 context operation throws a TypeError, crashing the application. (CVE-2026-12644)

Solution

Update the ts-deepmerge library and its related packages to version 8.0.0 or later.
