Details

Gumroad before 2026.07.06.2 contains a broken access control vulnerability in the PurchasesController that allows authenticated sellers to manipulate purchase access for other sellers' products by sending PUT requests to the revoke_access and undo_revoke_access actions without seller ownership validation. Attackers can modify the is_access_revoked status on arbitrary purchases to unauthorized revoke or restore buyer access to products they do not own.

Severity

6.5 (Medium)
