SCA: security update for graphql-scalars (GHSA-x8rm-f576-gq67)

high Tenable Cloud Security Plugin ID 477773

Description

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

 - GraphQL Scalars is a library of custom GraphQL scalars for creating precise type-safe GraphQL schemas.
 From 1.24.1 until 2.0.1, GraphQLPhoneNumber in src/scalars/PhoneNumber.ts uses ambiguous nested digit
 quantifiers that backtrack exponentially when a PhoneNumber value contains a run of digits followed by a
 character that makes the match fail. GraphQL evaluates parseLiteral during document validation and
 parseValue during variable coercion before resolver authentication or authorization, so a small
 unauthenticated request can block the Node.js event loop and stall the server process. serialize is also
 affected when unvalidated stored values are returned through the scalar. This issue is fixed in version
 2.0.1. (CVE-2026-115887)

Solution

Update the graphql-scalars library and its related packages to version 2.0.1 or later.
