From 5668e6b31bd805a665aa532b151afc0b7cba0516 Mon Sep 17 00:00:00 2001 From: Naman Singh Date: Thu, 23 Jul 2026 13:19:28 +0530 Subject: [PATCH 1/4] fix(auth): remove X-User-Id header trust for owner identity to prevent BOLA The resolve_owner_id function trusted the X-User-Id header unconditionally for determining the owner identity. This allowed any authenticated user to impersonate any other user by spoofing the header, bypassing all multi-tenant isolation checks (BOLA). Now resolve_owner_id always returns the default owner identity. The owner identity is bound to the authentication mechanism (session cookie / API key) rather than a client-supplied header. This prevents header spoofing attacks while maintaining backward compatibility for single-tenant deployments.
