CVE-2026-128030: OpenMage magento-lts before 20.18.2 Insufficient Session Expiration After API User Deactivation

Published Nov 13, 2026

Updated

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an insufficient session expiration vulnerability because MageApiModelSession::renewBySessId() never checks apiuser.isactive 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.

Frequently Asked Questions

1

Which releases address this issue?

The issue is addressed in OpenMage magento-lts 20.18.2 and 21.0.0-beta3. Affected releases are versions before 20.18.2 and 21.0.0-beta1 through before 21.0.0-beta3.

2

What must an attacker already possess to exploit this?

An attacker needs an existing SOAP/XML-RPC API session or REST OAuth access token. The issue allows that previously issued credential to remain usable after the related API or admin user is deactivated.

3

Does deactivating an API user or rotating API keys immediately remove existing access?

No. In affected versions, existing SOAP/XML-RPC sessions and OAuth access tokens can retain API access after deactivation or API key rotation, including access to read and modify customer, order, and catalog data.
