AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L
Renderer-compromise prerequisite drives AC:H; UI spoofing affects both confidentiality (phishing) and integrity (falsified UI), not availability.

Incorrect authorization in Navigation in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to spoof UI elements via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Incorrect authorization in Chrome's Navigation component (versions prior to 153.0.8010.36) allows a remote attacker who has already compromised the renderer process to spoof browser UI elements - such as the address bar or security indicators - via a crafted HTML page. This is a chained exploit step, not a standalone vulnerability: renderer-level code execution via a separate flaw is a hard prerequisite. …

Vulnerability AssessmentAI
| Exploitation | A previously compromised Chrome renderer process is an explicit, non-negotiable prerequisite - stated directly in the CVE description as 'a remote attacker who had compromised the renderer process.' Without prior renderer-level code execution (via a separate, independent vulnerability), this flaw cannot be triggered. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.2 (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L) appropriately reflects the constrained exploitability of this flaw - AC:H captures the mandatory renderer-compromise prerequisite, which substantially limits real-world risk. … 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 | Update Google Chrome to version 153.0.8010.36 or later using Chrome's built-in updater (chrome://settings/help) or enterprise distribution tooling (Google Admin, Intune, or similar MDM). … Detailed patch versions, workarounds, and compensating controls in full report. |
