Renderer pre-compromise as a mandatory prerequisite constitutes high attack complexity (AC:H), overriding the vendor's AC:L; all other metrics are retained.
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 StorageAccessAPI 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 StorageAccessAPI enables an attacker who has already compromised the renderer process to exfiltrate cross-origin storage data via a crafted HTML page, affecting all Chrome versions prior to 152.0.7977.65. The vulnerability is rated medium severity (CVSS 4.3) and requires both user interaction and a pre-existing renderer compromise, making it a second-stage chained exploit component rather than a standalone initial access vector. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two compounding prerequisites are required: first, the victim user must interact with a crafted HTML page (UI:R - non-passive user visit required); second, and critically, the attacker must have already compromised the Chrome renderer process through a separate vulnerability before this flaw can be leveraged. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 medium score is broadly consistent with a constrained exploit chain, but a notable discrepancy exists: the vendor CVSS vector carries PR:N (no prior privileges), while the CVE description explicitly states the attacker must have already compromised the renderer process - a high-barrier prerequisite that the AC:L rating undersells. … 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, which resolves the improper input validation in StorageAccessAPI. … Detailed patch versions, workarounds, and compensating controls in full report. |
