CVE-2023-26235Public exploitNetwork attack vector

Cross-site scripting via IPC file arguments

Published Feb 20, 2023 · Updated Mar 17, 2025

Cross-site scripting in JD-GUI 1.6.6 allows remote attackers to render controlled HTML via crafted serialized file arguments. InterProcessCommunicationUtil deserializes a String array from TCP port 20156 and passes its values to MainController.openFiles, whose error dialog renders newline-prefixed HTML from an invalid path. Exploitation requires single-instance mode and a reachable listener; rendered image tags can initiate outbound requests from the host.
