description

LearnPress versions through 4.4.10 deserialize attacker-controlled data associated with the checkout process. An unauthenticated attacker may inject PHP objects when the site's checkout AJAX functionality is publicly reachable.

mitigation

Update LearnPress to a vendor-confirmed release later than 4.4.10. Until then, disable or restrict public checkout functionality where operationally feasible.
