CVE-2026-128053
OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains a reflected cross-site scripting vulnerability in its error pages, which print SCRIPT_NAME-derived URLs built by errors/processor.php without escaping. Unauthenticated attackers can craft links that trigger uncaught exceptions on servers deriving SCRIPT_NAME from the request path, executing script in the storefront origin within victims' browsers.
