SCA: security update for @graphql-tools/executor-legacy-ws (GHSA-6fw5-9hq8-w87g)

high Tenable Self-Hosted Container Security Plugin ID 472975

Description

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

 - GraphQL Tools provides utilities for building, stitching, and mocking GraphQL schemas. Prior to 1.1.35,
 the executor-legacy-ws buildWSLegacyExecutor() function hardcodes TLS certificate rejection off for
 Node.js connections to wss:// endpoints. Applications using the executor directly, or url-loader with
 SubscriptionProtocol.LEGACY_WS, can therefore accept an attacker-controlled certificate when a network-
 positioned attacker intercepts the connection. Authentication material in connectionParams or headers can
 be disclosed, and subscription data can be modified. Browser WebSocket clients are unaffected because
 browsers enforce certificate validation. This issue is fixed in version 1.1.35. (CVE-2026-103921)

Solution

Update the @graphql-tools/executor-legacy-ws library and its related packages to version 1.1.35 or later.
