Snipe-IT is an IT asset/license management system. Prior to 8.6.2, when Full Multiple Companies Support and scope_locations_fmcs are enabled, the API location creation endpoint detects an invalid parent-child company mismatch but does not return immediately, allowing creation of a child location under a parent location from a different company. This issue is fixed in version 8.6.2.
