Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
AC:H because exploitation requires a pre-existing renderer compromise and a crafted page; UI:R for page load; S:C and C/I/A:H reflect full sandbox escape into the browser process.

Integer overflow in Chromecast in Google Chrome prior to 150.0.7871.47 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 before 150.0.7871.47 lets an attacker who has already compromised the renderer process break out of the sandbox via a crafted HTML page, escalating from renderer-level code execution to the more privileged browser process. Google rates the Chromium severity High and the CVSS is 9.6 due to the scope change; however, EPSS is only 0.21% (11th percentile) and there is no public exploit identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have ALREADY compromised the Chrome renderer process (this is explicitly stated: 'a remote attacker who had compromised the renderer process'), making this a chained, second-stage sandbox-escape rather than an independent entry point. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict in an instructive way. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises Chrome's renderer via a separate memory-corruption bug when the victim visits a malicious site, then serves a crafted HTML page that triggers the integer overflow in the Chromecast component to corrupt memory in a higher-privilege context and escape the sandbox, gaining code execution at the browser-process level. No public exploit is currently available, and success depends on already holding renderer-level control. |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms; Chrome typically auto-updates, so verify via chrome://settings/help and relaunch to apply. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Begin deployment of Chrome version 150.0.7871.47 or later; prioritize endpoints with Chromecast connectivity or privileged user accounts. …
