AC:H reflects the mandatory prior renderer-process compromise; S:C reflects cross-origin scope change from the origin policy bypass.
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.

Improper input validation in Preload 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
Web origin policy bypass in Google Chrome's Preload component (versions prior to 152.0.7977.65) enables a remote attacker who has already compromised the renderer process to read cross-origin data via a specially crafted HTML page. Classified as CWE-20 (Improper Input Validation) with a vendor-assigned CVSS score of 4.3 (Medium), the vulnerability is a second-stage attack primitive rather than a standalone exploit - requiring prior renderer compromise as a hard prerequisite. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two distinct prerequisites: first, the attacker must have already achieved code execution within the Chrome renderer process via a separate, independent vulnerability - this is the critical gate and is not trivial. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-supplied CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N = 4.3) assigns Low attack complexity, which understates the real-world bar: the description explicitly requires a compromised renderer process as a hard prerequisite, making this a second-stage exploit that can only be chained after a separate renderer vulnerability is successfully triggered. … 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 152.0.7977.65 or later, available via the browser's built-in update mechanism (Help > About Google Chrome) or through the Google Chrome Enterprise management console for fleet deployments. … Detailed patch versions, workarounds, and compensating controls in full report. |
