  1. CVE-2026-114606 5.6 Moyenne

    jgraph drawio-desktop

    draw.io Desktop is the official Electron build of draw.io. Prior to 31.4.4, draw.io Desktop is vulnerable to arbitrary local-file disclosure through the Electron main process's read-side IPC handlers. The readFile, getFileDrafts, getBkpFile, fileStat, isFileWritable, checkFileExists, and watchFile actions operate on a renderer-chosen filesystem path with no blessed-path (assertWritablePath) authorization. The only gates are validateSender — a URL-prefix origin check — plus, for readFile alone, a content "sniff" and a lexical appBaseDir prefix block. The write-side handlers (saveFile, writeFile, saveDraft, deleteFile) are all protected by assertWritablePath; the read side is not. The result is a read/write authorization asymmetry: any frame executing in the app's file:// origin can read the contents of local files that the same origin is explicitly forbidden to write. This issue is fixed in version 31.4.4.

  2. CVE-2026-114124 3.9 Faible

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9, frame data received from the GPU process for macOS offscreen rendering was not fully validated by the main process. An attacker who had separately gained code execution in the GPU process could provide inconsistent frame geometry and cause the main process to read out-of-bounds memory while producing paint event images, disclosing memory or crashing the application. This issue is fixed in versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9.

  3. CVE-2026-114122 3.9 Faible

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9, frame data received from the GPU process for webContents.beginFrameSubscription was not fully validated by the main process. An attacker who had separately gained code execution in the GPU process could supply inconsistent frame geometry and cause the main process to read out-of-bounds memory while producing captured frame images, disclosing memory or crashing the application. This issue is fixed in versions 42.11.6, 43.7.3, 44.4.3, and 45.0.0-alpha.9.

  4. CVE-2026-114121 5.4 Moyenne

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5, requests to open external protocol URLs could be attributed to a document other than the one that initiated them, causing the requestingUrl passed to session.setPermissionRequestHandler to identify trusted content for a launch requested by untrusted content. An application that grants openExternal based on the requesting origin and allows untrusted content to open or navigate windows could therefore allow that content to launch an OS-registered external application. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5.

  5. CVE-2026-113800 5.4 Moyenne

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5, hid and usb permission checks made from an iframe caused setPermissionCheckHandler to receive the top-level frame's origin and details instead of the requesting frame's. An application that delegated hid or usb to a cross-origin untrusted iframe and allowed device access with origin-based logic could therefore grant that embedded frame access intended for the top-level page. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.5.

  6. CVE-2026-113798 5.4 Moyenne

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13, pointerLock permission requests from some cross-origin iframes caused session.setPermissionRequestHandler() to receive the top-level frame's requestingUrl and isMainFrame values instead of those of the requesting frame. An application that embeds untrusted iframe content and grants pointer lock based on the requesting origin could therefore grant the permission under the top-level page's identity. Applications that deny pointerLock for untrusted embedded content are not affected. This issue is fixed in versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13.

  7. CVE-2026-113797 3.1 Faible

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.1, 43.5.1, 44.1.1, and 45.0.0-alpha.4, chrome.tabs.query() returned each tab's url and title to extensions that had neither the tabs permission nor matching host permissions. An application that loaded an extension it did not fully trust through session.extensions.loadExtension could therefore allow that extension to read the URL and title of every webContents in its session. This issue is fixed in versions 42.11.1, 43.5.1, 44.1.1, and 45.0.0-alpha.4.

  8. CVE-2026-113796 4.2 Moyenne

    electron

    Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6, Electron treated pages opened into a new window from links as application-initiated navigations instead of preserving the page containing the link as the initiator. The resulting top-level request could be classified as same-site, causing SameSite=Strict cookies to be sent and Sec-Fetch-Site not to identify the initiating page. An application that loads untrusted content and permits it to open new windows could therefore allow that content to make a credentialed request to another site that relies on SameSite cookies for CSRF protection. This issue is fixed in versions 42.11.3, 43.7.0, 44.3.0, and 45.0.0-alpha.6.
