Network-reachable via crafted page requiring no authentication, but passive user navigation is mandatory; impact is partial cross-origin data disclosure only, no integrity or availability consequence.
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.

Inappropriate implementation in Autofill in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's Autofill subsystem (versions prior to 151.0.7922.72) enables remote attackers to extract sensitive cross-origin information by directing a user to a specially crafted HTML page. The root cause is an inappropriate implementation within Autofill that fails to enforce proper origin boundaries (CWE-346), allowing page-level interactions to surface data from contexts the page should not be able to read. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: the victim must actively navigate to an attacker-controlled HTML page in an unpatched Chrome browser (UI:R in CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) reflects a network-reachable, low-complexity, zero-privilege attack that nonetheless requires user interaction (UI:R), caps out at low confidentiality impact (C:L), and has no integrity or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a domain and serves a page containing crafted HTML that abuses the Autofill implementation flaw to trigger cross-origin data observation. A targeted user is sent a phishing link and, upon visiting the page in an unpatched Chrome browser, the page exfiltrates partial data from a cross-origin context (such as values Autofill would populate) back to the attacker's server. … |
| Remediation | Vendor-released patch: Chrome 151.0.7922.72. … Detailed patch versions, workarounds, and compensating controls in full report. |
