  1. CVE-2026-82649 7.0 Élevée

    siyuan-note siyuan

    SiYuan Windows installer before version 3.8.1 (affected versions >= 2.0.14) contains an uncontrolled search path element vulnerability in its NSIS installer, which invokes system executables such as TASKKILL by name rather than by absolute path. Because NSIS nsExec::Exec resolves these calls using a search path that includes the installer's own launch directory ahead of System32, an attacker who plants a malicious executable (e.g., a renamed TASKKILL.exe) in that directory can have it executed when the installer runs. These calls occur in electron-builder's preInit hook before the license page is displayed, and with an all-users (elevated) install the planted binary executes with an elevated token, resulting in local privilege escalation.

  2. CVE-2026-53579 6.1 Moyenne

    TriliumNext Trilium · Triliumnotes trilium

    Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the default-on "Safe import" filter sanitizes HTML only for text notes and excludes the book note type, whose content is stored without sanitization and later rendered as HTML, allowing an attacker-supplied import archive to embed a payload that executes as script. A book note's content is routed through the same rendering path as text notes and injected into the page with jQuery's html method when the note is shown as a grid-view preview card, so a malicious note survives Safe import and runs as soon as the victim opens the containing note. On the desktop client the Electron renderer runs with Node integration enabled, so the injected JavaScript escalates from cross-site scripting to full remote code execution on the victim's machine. This issue is fixed in version 0.104.0.

  3. CVE-2026-53578 6.1 Moyenne

    Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the default-on "Safe import" filter sanitizes HTML only for text notes and excludes the mindMap note type, whose JSON content is stored without sanitization, allowing an attacker-supplied import archive to embed a payload that renders as arbitrary HTML. A mind map node can carry a dangerouslySetInnerHTML property that the Mind Elixir library assigns directly to a node's innerHTML, so a malicious note survives Safe import and executes script as soon as the victim opens the imported mind map. On the desktop client the Electron renderer runs with Node integration enabled, so the injected JavaScript escalates from cross-site scripting to full remote code execution on the victim's machine. This issue is fixed in version 0.104.0.

  4. CVE-2026-48996 6.1 Moyenne

    TriliumNext Trilium · Triliumnotes trilium

    Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the default-on "Safe import" filter does not sanitize note titles, and the GeoMap note view interpolates a marker note's title into raw HTML that is rendered as innerHTML, allowing an attacker-supplied import archive to inject script that runs when the map is displayed. Because Safe import neutralizes scripts but never escapes titles, a note whose title contains an HTML event-handler payload survives the import and executes as soon as the victim opens the GeoMap that renders its marker. On the desktop client the Electron renderer runs with Node integration enabled, so the injected JavaScript escalates from cross-site scripting to full remote code execution on the victim's machine. This issue is fixed in version 0.104.0.
