CVE-2026-45733
Description
Trilium Notes is a cross-platform, hierarchical note taking application focused on building large personal knowledge bases. Prior to 0.103.0, the #iconClass label value is returned raw by getNoteIcon() and inserted without HTML attribute encoding into class attributes in apps/client/src/widgets/quick_search.ts and apps/client/src/services/note_autocomplete.ts, allowing a stored payload to execute automatically when a victim opens a new tab or uses Ctrl+J and, because Electron enables nodeIntegration and disables contextIsolation, run operating-system commands as the victim. This issue is fixed in version 0.103.0.
