Descripción técnica

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.

———webpack-dev-server is a development server that provides live reloading for webpack projects. In versions before 5.2.7 and in version 6.0.0, when a proxy entry is configured to forward WebSockets, the server forwards non-HMR WebSocket upgrade requests to the proxy target without validating the Host or Origin headers, so the allowedHosts protection does not apply to those proxied upgrades. A malicious web page visited by a developer can open a cross-origin WebSocket through the dev server and read from and write to the proxied backend, even when the server is bound to loopback. The issue is fixed in webpack-dev-server 5.2.7 and 6.1.0, where proxied WebSocket upgrades pass the same Host and Origin validation as the HMR WebSocket, and users should upgrade to one of those versions or later. As a workaround, omit WebSocket forwarding from proxy entries that do not need it and scope the proxy to specific paths.5h CVE-2026-114125—

———Storybook is a frontend workshop for building user interface components and pages in isolation. From 8.0.0 until 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6, a malicious website can interact with the preview of a running Storybook development server. Insufficient iframe embedding and message-origin restrictions can allow attacker-controlled events to reach the running preview. A developer must visit the malicious website and interact with the injected interface. The attack can cause unauthorized changes to story files and, if a changed file is later executed by a local runtime, arbitrary code execution with the developer's privileges. This issue is fixed in 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6.1d CVE-2026-1138005.4 MED

———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.5.1d CVE-2026-1137985.4 MED

———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.13.1d CVE-2026-1123777.4 ALT

——2CCC Attestation SIG attested-tls-poc through commit 731ca82 fails to bind early attestation Evidence to the TLS connection, allowing attackers to relay valid Evidence from a genuine attester. Attackers holding an extracted attested TLS private key can forward the relying party's nonce to a genuine attester and replay its Evidence to impersonate the attested workload and intercept data.2d CVE-2026-1121014.3 MED

——5A vulnerability was determined in BlackBeltTechnology pi-agent-dashboard up to 0.8.0. The affected element is an unknown function of the file /BlackBeltTechnology/pi-agent-dashboard of the component WebSocket Gateway. Executing a manipulation of the argument cwd can lead to origin validation error. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 0.9.0 is sufficient to fix this issue. This patch is called 48fd0bad5adfe76af9736599699d51a5f60019f6. It is recommended to upgrade the affected component.3d
