AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Kept AV:N/UI:R/S:C with full impact for the sandbox escape, but raised AC:L to AC:H because exploitation depends on first compromising the renderer, a non-trivial precondition.

Insufficient validation of untrusted input in Chromecast in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome's Chromecast component (versions prior to 151.0.7922.72) allows a remote attacker who has already compromised the renderer process to break out of the sandbox via a crafted HTML page. Rated High by Chromium and scored CVSS 9.6 due to scope change, it is a classic second-stage browser exploit chained after an initial renderer bug. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised Chrome's renderer process (typically via a separate renderer RCE) - this CVE alone is not a standalone remote exploit but the sandbox-escape link in a chain. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and must be read together. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer vulnerability to gain code execution inside Chrome's sandboxed renderer when a victim visits a malicious site. Using this CVE, the attacker then sends crafted, insufficiently-validated input to the Chromecast component to escape the sandbox and run code in the more-privileged browser process. … |
| Remediation | Vendor-released patch: Google Chrome 151.0.7922.72. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit your inventory management systems and browser deployment tools to identify all Chrome instances running versions prior to 151.0.7922.72 across endpoints, servers, and managed devices. …
