AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Renderer compromise is a non-trivial chained prerequisite raising AC to H; UI spoofing yields only low integrity impact with no C or A.

Insufficient validation of untrusted input in PopupBlocker in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
UI spoofing in Google Chrome's PopupBlocker component (all versions prior to 150.0.7871.47) enables a remote attacker who has already compromised the Chrome renderer process to manipulate browser UI elements through a crafted HTML page. The integrity impact is limited to UI deception - no code execution, credential theft, or availability impact is possible through this flaw alone. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already achieved code execution within Chrome's renderer process via a separate, independent vulnerability - this is a hard prerequisite explicitly stated in the CVE description ('remote attacker who had compromised the renderer process'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) scores the outer attack surface but does not fully capture the material prerequisite disclosed in the description: renderer process compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has separately exploited a memory-corruption vulnerability to gain code execution inside Chrome's sandboxed renderer process then delivers a crafted HTML page that sends malformed IPC messages to the PopupBlocker in the browser process. The insufficient input validation allows the attacker to inject spoofed browser UI chrome - such as a fake address bar, permission prompt, or trusted-site dialog - potentially deceiving the victim into disclosing credentials or approving a sensitive action. … |
| Remediation | Upgrade Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch per Google's stable channel update advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
