Remotely triggered via crafted HTML (AV:N, AC:L, PR:N, UI:R); spoofing yields only integrity impact with no confidentiality or availability consequence (C:N, I:H, A:N).

Inappropriate implementation in Paint in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI spoofing in Google Chrome's Paint rendering component (versions prior to 150.0.7871.47) enables remote attackers to misrepresent browser interface elements through a specially crafted HTML page, with the victim's visit being the sole prerequisite. The CVSS vector confirms high integrity impact (I:H) with no confidentiality or availability exposure, consistent with CWE-451 misrepresentation of critical UI information rather than code execution. No public exploit has been identified and EPSS sits at the 7th percentile (0.17%), indicating very low near-term exploitation probability; a vendor patch is confirmed available in the Chrome stable channel.
Technical ContextAI
The vulnerability resides in Chrome's Paint subsystem - the rendering pipeline stage responsible for drawing composited UI frames to the display surface. CWE-451 (User Interface Misrepresentation of Critical Information) identifies the root cause class: the Paint implementation fails to correctly enforce boundaries or trusted rendering context, allowing attacker-controlled HTML content to influence the appearance of browser chrome elements such as the address bar, origin indicators, or security dialogs. This is a classic browser UI confusion bug where the renderer does not sufficiently isolate page-controlled pixels from browser-controlled UI pixels. Affected CPE corresponds to Google Chrome for desktop platforms (Windows, macOS, Linux) in the stable channel prior to build 150.0.7871.47.
RemediationAI
Update Google Chrome to version 150.0.7871.47 or later via the Chrome stable channel; this is the confirmed vendor-released patch per the advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Chrome's auto-update mechanism will apply this in most managed and consumer environments, but administrators should verify deployed versions via fleet management tooling. No vendor-documented workaround exists for this specific Paint rendering flaw. As a compensating control for high-risk environments where immediate patching is not possible, restricting browser access to untrusted or unknown web origins via a web proxy or DNS filtering layer can reduce exposure surface, though this does not eliminate the vulnerability and imposes usability trade-offs. Browser isolation technologies (e.g., remote browser isolation) can also contain the impact of UI spoofing by rendering external pages in an isolated context.
