AC raised to H because renderer process compromise is a required prerequisite condition outside the attacker's unilateral control for this specific CVE; all other metrics follow the description.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Missing authorization in Viz in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
The Viz compositor component in Google Chrome prior to 152.0.7977.65 can be exploited by an attacker who has already achieved renderer process compromise to bypass Chrome's web origin policy via a crafted HTML page. This is a chained exploit primitive, not a standalone initial-access vector - it escalates an existing renderer foothold into cross-origin data access. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already independently compromised the Chrome renderer process through a separate, unrelated vulnerability - this CVE does not provide initial renderer access on its own. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 score (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) captures network accessibility and low complexity but is potentially misleading as a standalone signal: the CVE description explicitly states that renderer process compromise is a prerequisite, meaning this vulnerability is the second link in an exploit chain rather than a direct entry point. … 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: Chrome 152.0.7977.65. … Detailed patch versions, workarounds, and compensating controls in full report. |
