Improper input validation in Chromium in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to spoof UI elements via crafted network traffic. (Chromium security severity: Low)
AnalysisAI
UI spoofing in Google Chrome prior to 153.0.8010.36 permits a remote attacker who has already compromised the renderer process to present falsified browser interface elements to the user through crafted network traffic. The root cause is improper input validation (CWE-20) in the Chromium rendering engine, allowing a compromised renderer to influence UI presentation in ways the browser should reject. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation has one hard prerequisite: the attacker must have already achieved code execution within the Chrome renderer process via a separate, independently exploitable vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Quantitative signals uniformly indicate low urgency: CVSS 4.3 with S:U and I:L only, EPSS at 0.16% (6th percentile), Chromium internal severity rated 'Low,' no CISA KEV listing, and no public POC identified at time of analysis. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is upgrading Google Chrome to version 153.0.8010.36 or later via the stable channel update documented at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
