Inventory data modification via imported-flag validation bypass
Published Mar 31, 2026 · Updated Mar 31, 2026
CSRF and input-validation bypass in Admidio before 5.0.8 allows remote authenticated users to write arbitrary inventory item data. ItemService::save trusts the POST-supplied imported flag, skips CSRF-token lookup and FormPresenter validation, and persists raw form values. Inventory access is required for a direct request; a remote attacker can instead induce a logged-in inventory user to submit a cross-site request that creates or changes stored item data.
