Adjacent vector reflects LAN-only reachability; PR:N confirmed by CVSS input; C:L reflects partial cross-origin data disclosure 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.

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 component allows an unauthenticated attacker positioned on the same local network segment to read data from origins they should not have access to via maliciously crafted network traffic. All Chrome versions prior to 151.0.7922.72 are affected. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be on the same local network segment (LAN or Wi-Fi) as the targeted Chrome user - remote Internet-based exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low-to-moderate. … 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 as a target user sends specially crafted Cast protocol messages to the victim's Chrome browser. The insufficient input validation in the Cast component causes Chrome to process the malicious traffic in a way that exposes data from a cross-origin context - for example, content or tokens from an already-open web page - back to the attacker. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which contains the vendor-released fix per the Stable Channel Update advisory at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
