Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Solidus_frontend and solidus_api, versions before 2.8.6, from 2.9.0 before 2.9.6, and from 2.10.0 before 2.10.2, allow a customer to submit crafted checkout requests that change the order's shipping address without the shipping costs being recalculated for the new zone. Any authenticated customer who can reach checkout can exploit this to pay a lower shipping rate, or to move to an address in a zone the store meant to exclude. Upgrade solidus_frontend and solidus_api to 2.8.6, 2.9.6, or 2.10.2, depending on the release line in use.
