10 CVE

  1. CVE-2026-100645 8.0 Élevée

    siyuan-note siyuan

    SiYuan versions 3.7.0 before 3.8.4 contain a stored cross-site scripting vulnerability in gallery and kanban database renderers where field descriptions are not escaped in aria-label attributes. In the Electron desktop app with nodeIntegration enabled, attackers can inject JavaScript that calls Node.js child_process APIs to execute arbitrary commands with user privileges.

  2. CVE-2026-100643 8.0 Élevée

    siyuan-note siyuan

    SiYuan versions before v3.8.4 fail to properly escape four stored Attribute View values in textarea elements, allowing authenticated attackers to inject JavaScript by modifying field descriptions, template sources, select option descriptions, or footer calculation templates. Attackers can execute stored JavaScript when other users open affected database menus, and in the Electron desktop app with nodeIntegration enabled, this leads to command execution with SiYuan process privileges.

  3. CVE-2026-100641 8.0 Élevée

    siyuan-note siyuan

    SiYuan before v3.8.4 does not HTML-escape stored flashcard block content before interpolating it into the card-manager list markup. Block content returned by /api/riff/getRiffCards is inserted into a card item template in app/src/card/viewCards.ts and assigned to listElement.innerHTML, so content such as <img src=invalid onerror=...> becomes an executable event-handler attribute. Because the SiYuan desktop (Electron) main window is created with nodeIntegration enabled and contextIsolation disabled, an administrator who opens the card manager on a workspace containing attacker-supplied flashcard content (for example introduced through contribution or import) executes the attacker's script in a privileged renderer, which can lead to arbitrary code execution on the host. The affected endpoint remains behind authentication and administrator-role checks; this is an untrusted-content-to-privileged-renderer issue, not an authorization bypass.

  4. CVE-2026-100639 8.8 Élevée

    siyuan-note siyuan

    SiYuan v3.8.3 fails to HTML-escape the data-subtype attribute when generating gutter-button markup (app/src/protyle/gutter/button.ts, assigned via innerHTML in app/src/protyle/gutter/index.ts) from content pasted as plain-text Markdown containing a Kramdown inline attribute list (IAL). Because the shared Lute renderer parses Kramdown IAL from text/plain input, an attacker-supplied Markdown snippet using entity-encoded quotes in data-subtype breaks out of the attribute value when the gutter markup is re-parsed by the browser, injecting additional attributes such as autofocus and onfocus. If a victim pastes the crafted Markdown and the affected gutter control receives focus, the injected handler executes; in the Electron desktop application, where the main BrowserWindow enables Node integration and disables context isolation, this results in JavaScript execution with renderer Node.js privileges (remote code execution). Fixed in v3.8.4.

  5. CVE-2026-100634 4.7 Moyenne

    siyuan-note siyuan

    SiYuan before v3.8.4 does not validate the sender or restrict recipients in the 'siyuan-send-windows' IPC handler of the Electron main process (app/electron/main.js). The handler ignores event.sender and forwards any received payload to every BrowserWindow returned by BrowserWindow.getAllWindows(), including windows belonging to other opened workspaces. A renderer connected to an attacker-controlled remote kernel can therefore send {cmd: "lockscreenByMode"} and have it delivered across the workspace boundary; a sibling workspace window whose lockScreenMode is set to 1 invokes lockScreen(). Repeated messages allow the remote workspace to repeatedly lock unrelated local workspace windows, causing a limited denial of service. No confidentiality, integrity, or code-execution impact was observed.

  6. CVE-2026-97366 6.3 Moyenne

    jhen0409 react-native-debugger

    A security flaw has been discovered in jhen0409 react-native-debugger up to 0.14.0. The impacted element is the function openDevTools of the file electron/window.js of the component Open in Editor Handler. The manipulation of the argument host results in os command injection. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

  7. CVE-2026-93405 6.1 Moyenne

    Foundry376 Mailspring

    Mailspring is a fast, cross-platform, open-source email client. Prior to 1.17.0, attachment quick preview converts Markdown, DOCX, and XLSX attachments with Snarkdown, Mammoth, and SheetJS and inserts the resulting HTML into the preview document through innerHTML without sanitization. A remote sender can craft a supported attachment whose converted HTML executes script when a recipient opens quick preview. The preview renderer has no direct Node or Electron access, but injected script can reach the IPC surface exposed to the quick-preview renderer. This issue alone provides script execution in the preview renderer; separate path-traversal and renderer-controlled file-write vulnerabilities are required for the documented persistent code-execution chain. This issue is fixed in version 1.17.0.

  8. CVE-2026-18104 3.3 Faible

    IBM Db2 Mirror for i

    IBM Db2 Mirror for i 7.6, 7.5, and 7.4 could allow a local attacker to obtain sensitive information due to the use of the AES Electronic Codebook (ECB) mode for encryption.

  9. CVE-2026-50228 6.1 Moyenne

    Acer NitroSense V5

    An unauthenticated local attacker can connect to the Electron DevTools endpoint exposed by Acer NitroSense software (versions up to and including 5.2.63) on localhost TCP port 9993. Because Chromium remote debugging is enabled in the production application, the attacker can execute JavaScript in the privileged application context and achieve arbitrary code execution.

  10. CVE-2026-12718 9.8 Critique

    Karel Electronic Industry and Trade Inc. KarelIPS

    Improper neutralization of special elements used in an SQL command ('SQL injection') vulnerability in Karel Electronic Industry and Trade Inc. KarelIPS allows Blind SQL Injection. This issue affects KarelIPS: through 22092026. NOTE: The vendor was contacted and it was learned that the product is not supported.
