Description

Capgo before 12.128.2 contains an authorization flaw in POST /private/create_device that accepts a caller-supplied org_id parameter without validating it matches the target app's owner organization. Authenticated attackers can create device records for an application using a foreign organization identifier, bypassing the intended org/app authorization boundary.
