fix(coderd): require deployment-wide workspace read for WatchAllWorkspaceBuilds endpoint - #26985
Merged
Conversation
…kspacebuilds The experimental /api/experimental/watch-all-workspacebuilds endpoint streamed build events for every workspace in the deployment without any per-item authorization. Any authenticated user could enumerate all workspace names and observe build activity across organizations they do not belong to. Gate the endpoint on deployment-wide workspace read (rbac.ResourceWorkspace.All(), granted by Owner or Template Admin) so the firehose is only accessible to sufficiently privileged users. Addresses SEC-A6B05AB854 / ANT-2026-22462.

This PR adds an RBAC auth check to the
WatchAllWorkspaceBuildsendpoint/function. Even though this endpoint is gated behind an experimental feature flag, and currently only used for scaletesting, it should still require some additional level of permissions. Currently any authenticated client can hit that endpoint and receive updates for all workspace builds for the whole deployment.With this PRs changes the endpoint will be gated behind the deployment wide workspace read all permission, which is limited to just deployment owners and template admins. Org admins and lower would no longer be able to use this endpoint.
