CVE-2026-46691: Auth Bypass (CVSS 6.5)

Description

EspoCRM is an open source customer relationship management application. Prior to 9.3.7, an authenticated user with Import scope access can send POST /api/v1/Import/{id}/exportErrors with another user's import identifier and retrieve an attachment identifier for a CSV containing rows from that import. The endpoint performs a scope-level check but omits the entity-level ownership check enforced by the Import AccessChecker and sibling Import endpoints. This issue is fixed in version 9.3.7.
