Description

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains a stored cross-site scripting vulnerability because admin pages render Dataflow profile link variables, tax rate titles, OAuth consumer names, and PayPal certificate filenames without escaping. An administrator restricted to one affected area can store script that runs when another administrator, including a full administrator, opens the page, reading the form key and performing actions with that administrator's privileges.
