      <title>CVE-2026-118665 — GraphQL Tools: Per-request connection parameters persist into later users' WebSocket authentications</title>
      <link>https://db.gcve.eu/vuln/cve-2026-118665</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ardatan graphql-tools, @graphql-tools executor-legacy-ws&lt;/p&gt;
&lt;p&gt;GraphQL Tools provides utilities for building, stitching, and mocking GraphQL schemas. Prior to version 1.1.36 of the GraphQL Tools legacy WebSocket executor package, buildWSLegacyExecutor in packages/executors/legacy-ws/src/index.ts retains request.extensions.connectionParams in the closure-scoped executorConnectionParams object after cleanupWebsocket closes a connection. When one executor is reused across different authorization contexts, a later request that omits a sensitive key can send an earlier caller&amp;#39;s Authorization or tenant value in its connection_init payload, causing the downstream server to authenticate the later caller as the earlier user. Applications that create a new executor for every request are not affected. This issue is fixed in version 1.1.36 of the GraphQL Tools legacy WebSocket executor package.&lt;/p&gt;</description>
