Network-delivered via crafted page (AV:N), user must visit the page (UI:R), SOP bypass yields only limited cross-origin data read with no integrity or availability impact.
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 Network in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Origin policy bypass in Google Chrome prior to 152.0.7977.65 exposes users to potential cross-site data leakage when a victim visits an attacker-controlled page. The Network component fails to properly validate input (CWE-20), enabling circumvention of the browser's web origin policy - a fundamental Same-Origin Policy enforcement mechanism - allowing a remote attacker to read data from origins other than the page's own. …

Vulnerability AssessmentAI
| Exploitation | The victim must actively visit or be redirected to a crafted HTML page while using Google Chrome prior to version 152.0.7977.65 (UI:R per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 4.3 (Medium) is consistent with a constrained SOP bypass: AV:N indicates network reachability, AC:L means no special conditions are required to trigger the flaw, but UI:R limits exploitation to scenarios where a victim actively visits a crafted page. … 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. |
