Missing authorization in Transactions Platform in Google Chrome prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process to spoof UI elements via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI spoofing in Google Chrome's Transactions Platform component lets a remote attacker who has already compromised the browser's renderer process render crafted HTML as trusted interface elements, deceiving the user. The flaw is a missing authorization check (CWE-862) affecting Chrome versions prior to 153.0.8010.47, and it is not reachable on its own: exploitation requires a separate, earlier renderer compromise plus the victim loading and interacting with the attacker's page (UI:R, AC:H). …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to FIRST compromise Chrome's renderer process through a separate, earlier vulnerability - this bug is not reachable on its own. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority, high-friction issue despite the CRITICAL-sounding 'missing authorization' label. … 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 | Vendor-released patch: upgrade Google Chrome to 153.0.8010.47 or later, as documented in the Chrome stable channel update advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0541751186.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
