DescriptionCVE.org

Inappropriate implementation in Geometry in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

UI spoofing via crafted HTML in Google Chrome's Geometry component (versions prior to 150.0.7871.47) enables remote attackers to misrepresent security-critical interface elements to users who are socially engineered into performing specific UI gestures. The flaw stems from an inappropriate implementation in Chrome's Geometry subsystem (CWE-451), affecting the integrity and availability of the browser interface at low impact levels. …

Vulnerability AssessmentAI

Exploitation Exploitation requires two explicit prerequisites: first, the victim must visit a crafted HTML page under attacker control; second, the victim must be convinced to perform specific UI gestures (the exact nature of which is not disclosed in available data, consistent with Chromium's responsible disclosure practice). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 4.2 (Medium) is supported by the vector CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts an HTML page that exploits the Geometry miscalculation to misrepresent UI elements - such as overlaying a fake permission dialog or spoofing the address bar - then distributes the link via phishing email or social media. The victim visits the page and is guided (through on-page instructions or visual cues) into performing specific UI gestures such as clicking or scrolling in a particular sequence. …
Remediation The primary remediation is to upgrade Google Chrome to version 150.0.7871.47 or later, as confirmed by the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report.
