Network-delivered via crafted page requiring active user visit; only limited cross-origin confidentiality leak 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.

Inappropriate implementation in Network 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 prior to version 151.0.7922.72 allows remote attackers to read data across origin boundaries by inducing a user to visit a specially crafted HTML page. The flaw resides in Chrome's network layer and is classified as CWE-346 (Origin Validation Error), meaning the browser fails to properly enforce origin boundaries during certain network operations. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires active user interaction: the victim must navigate to or be redirected to an attacker-controlled HTML page in a vulnerable Chrome instance (UI:R per CVSS). … 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 real but constrained risk profile: AV:N indicates network reachability but UI:R limits exploitation to scenarios where the victim actively visits a malicious page, ruling out fully passive or automated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a domain and hosts a crafted HTML page that exploits Chrome's improper origin validation to silently issue network requests and read responses from a cross-origin target (e.g., an internal corporate web application the victim is authenticated to). The attacker distributes the link via phishing email or malicious advertisement; when the victim opens it in a vulnerable Chrome version, the page exfiltrates partial data - such as CSRF tokens, session identifiers, or page content - back to the attacker-controlled server without triggering visible browser warnings. … |
| Remediation | The primary remediation is to update Google Chrome to version 151.0.7922.72 or later, which is confirmed as patched per the vendor advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
