 - Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the
 Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to
 20.18.0, Mage_ProductAlert_AddController::stockAction() reads the uenc query parameter and passes it
 directly to $this->_redirectUrl($backUrl) without calling $this->_isUrlInternal(). When the supplied
 product_id does not match any catalog product, the server issues an unvalidated HTTP 302 redirect to
 whatever URL was provided as uenc. This vulnerability is fixed in 20.18.0. (CVE-2026-42207)

Update the openmage/magento-lts library and its related packages to version 20.18.0 or later.
