CVE-2026-128030

OpenMage magento-lts before 20.18.2 Insufficient Session Expiration After API User Deactivation

  • High 7.4

Description

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an insufficient session expiration vulnerability because Mage_Api_Model_Session::_renewBySessId() never checks api_user.is_active and REST OAuth authorization never checks whether the admin user is active. Attackers holding an existing SOAP/XML-RPC session or OAuth access token retain API access after deactivation or API key rotation, reading and modifying customer, order and catalog data.
