Summary

PickMall lilishop through 4.4 contains an insecure direct object reference that lets authenticated sellers change other stores' product freight templates via PUT /store/goods/goods/freight. The freight functions update goods and SKUs by id without store-scoped checks, so sellers can bind their own templates to competitors' products and alter shipping charges. CISA SSVC data records a proof-of-concept, and the flaw is not in CISA's KEV catalog. Exploitation requires a valid seller account with low privileges, and no user interaction is required.
