CVE-2026-670796.4 MED—
——0HCL BigFix AEX is affected by a Clickjacking vulnerability, which could allow an attacker to embed the application within a malicious web page or iframe and trick users into performing unintended actions, potentially leading to unauthorized transactions or changes to their accounts.1dCVE-2026-77062—44.3%
——13The boneIO Black web interface lacks proper clickjacking protections. A remote attacker can embed the control panel in an iframe on a malicious web page and trick an authenticated user on the internal network into clicking buttons that activate relays, open gates, or control blinds. This can lead to unauthorized state changes with potential physical safety consequences. Critically, due to CVE-2026-77053 (authentication disabled by default), any user on the same internal network can trigger attacker-controlled actions by visiting the malicious website.
This issue was fixed in version 1.6.0.3dCVE-2026-114125—32.4%
——10Storybook 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.6.1dCVE-2026-600083.5 BAJ30.9%
——9Gitea's Jupyter notebook renderer inserts the notebook's language_info.name metadata into a CSS class attribute while disabling sanitization and rendering directly in the main document without an iframe sandbox. A malicious repository notebook can supply multiple CSS classes that create a viewport-covering overlay and intercept clicks when another user views it. The reported impact is UI redress; script execution was not demonstrated.15dCVE-2026-1092908.7 ALT24.2%
——7Open WebUI from 0.11.1 before 0.11.4 contains a stored cross-site scripting vulnerability in DocxPreview.svelte that allows authenticated users to execute script by uploading crafted DOCX attachments. Attackers can embed an OOXML altChunk HTML part or script-scheme hyperlink to steal a previewing administrator's session token from local storage and take over the instance.6dCVE-2026-1089013.5 BAJ10.2%
——3A vulnerability was found in Shenzhen HCC Technology MPOS M6 PLUS 1.31-N. Affected by this vulnerability is an unknown functionality of the component Display QR Code Rendering. Performing a manipulation of the argument alignment results in improper restriction of rendered ui layers. The attack can only be performed from the local network. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.16d
