+### Patch Changes

+- [#2957](https://github.com/graphql-hive/graphql-inspector/pull/2957)
+  [`ea2e18d`](https://github.com/graphql-hive/graphql-inspector/commit/ea2e18d7a8e561c6f37b9f3c03af6dd0b48de004)
+  Thanks [@wonda-tea-coffee](https://github.com/wonda-tea-coffee)! - Update GitHub Action runtime
+  from `node20` to `node24`.
+
+  GitHub Actions deprecated Node 20
+  (https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/) and
+  now runs `using: node20` actions on Node 24 by default. On Node 24, `globalThis.navigator` is a
+  built-in read-only getter, so the legacy `global.navigator = { userAgent: 'node.js' }` assignment
+  in the action bundle threw
+  `TypeError: Cannot set property navigator of #<Object> which has only a getter` at startup,
+  breaking every workflow that consumed this action.
+
+  This release removes the obsolete `global.navigator` assignment (Node 24 provides
+  `navigator.userAgent` natively), bumps `runs.using` to `node24` in `action.yml`, and regenerates
+  the bundle. Workflows that pin this action will now execute on the Node 24 runtime.
+
 ## 5.0.20
