## What changed and why? ### **Security** - Check namespaces in batch workflow ([CVE-2026-5199](https://www.cve.org/cverecord?id=CVE-2026-5199), LOW) ## How did you test it? - [x] built - [ ] run locally and tested manually - [ ] covered by existing tests - [x] added new unit test(s) - [x] added new functional test(s) <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Medium Risk** > Tightens namespace validation for privileged batcher activities to prevent cross-namespace request spoofing; mistakes here could block legitimate batch jobs or still leave gaps if other call paths use unvalidated namespaces. > > **Overview** > Adds strict namespace isolation checks to the batcher worker: `BatchActivityWithProtobuf` now validates that `NamespaceId` *and* any provided `Request.Namespace`/`AdminRequest.Namespace` match the worker’s bound namespace, and consistently uses that bound namespace for downstream frontend calls (including reset-by-type). > > Adds targeted tests: new unit tests to reject mismatched namespace strings and to assert `startTaskProcessor` uses the worker namespace for signals, plus a functional test ensuring a batch terminate in one namespace does not affect workflows in another. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 3a52696.
