UI spoofing in Google Chrome prior to 152.0.7977.65 allows unauthenticated remote attackers to misrepresent browser interface elements through a crafted HTML page, requiring only that a user visit the malicious content. Classified as CWE-451 (UI Misrepresentation of Critical Information), the flaw breaks the trust contract between the browser and user by rendering deceptive interface states - a classic phishing-enabler primitive. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to actively visit a crafted HTML page hosted by the attacker (UI:R - active user interaction is mandatory; drive-by exploitation via passive page load alone is insufficient without the user navigating to the malicious URL). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) reflects a network-accessible, low-complexity attack that nonetheless requires active user interaction and delivers only limited integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a convincing lookalike domain and hosts a crafted HTML page that exploits the rendering flaw to overlay or replace visible Chrome UI elements - such as an address bar segment or a security lock icon - with attacker-controlled content. A victim lured to the page via phishing email or malicious redirect sees what appears to be a trusted origin, submits credentials or sensitive information, and the attacker captures it through a backend form handler. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later; this is the vendor-released patch per the stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
