CVE-2026-10173Public exploitNetwork attack vector

Reflected XSS via unsanitized remote-source interpolation

Published May 31, 2026 · Updated May 31, 2026

Reflected XSS in Orthanc Explorer 2 1.12.0 and earlier allows remote attackers to execute JavaScript through a crafted URL. StudyList.vue copies the remote-source query value into a vue-i18n message rendered with v-html, which treats the unescaped value as HTML. No authentication or upload is required, but a user must open the link; execution occurs in the Orthanc Explorer browser context.
