Adjacent network vector reflects Cast protocol's LAN-only scope; C:L only as impact is cross-origin data leakage with 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.

Insufficient validation of untrusted input in Cast in Google Chrome prior to 151.0.7922.72 allowed an attacker on the local network segment to leak cross-origin data via malicious network traffic. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's Cast subsystem (versions prior to 151.0.7922.72) allows unauthenticated attackers on the same local network segment to extract sensitive cross-origin browser data via crafted network traffic. The insufficient input validation in the Cast component bypasses browser isolation boundaries, exposing data from origins the victim is actively browsing. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same local network segment as the target Chrome user (AV:A) - this is the primary limiting condition. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 (Medium) rating is well-calibrated for this issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker connected to the same Wi-Fi network or LAN segment as a Chrome user - for example, on a shared corporate guest network or public hotspot - crafts and transmits malicious Cast protocol network traffic toward the victim's Chrome browser. The insufficient validation in Chrome's Cast component processes the malformed packets and inadvertently exposes cross-origin data from the victim's active browsing session, potentially revealing authentication tokens, page content, or other sensitive information from origins the victim is accessing. … |
| Remediation | The primary remediation is to update Google Chrome to version 151.0.7922.72 or later, as documented in the stable channel update 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. |
