AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Remote crafted page, no privileges but required user interaction (UI:R); use-after-free fully compromises the sandboxed process, so S:U with C/I/A High.

Use after free in Cast Receiver in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandboxed remote code execution in Google Chrome's Cast Receiver component affects all desktop builds prior to 150.0.7871.47, where a use-after-free (CWE-416) can be triggered by luring a victim to a crafted HTML page. Google rates the Chromium severity as Medium because the resulting code execution is confined to the browser sandbox, though NVD scores it CVSS 8.8; there is no public exploit identified at time of analysis and EPSS exploitation probability is low at 0.27% (18th percentile).

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or navigate to an attacker-controlled HTML page (CVSS UI:R), and the target must be running Chrome earlier than 150.0.7871.47 with the Cast Receiver code path reachable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are moderate and internally consistent rather than alarming. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that abuses the Cast Receiver to free and then reuse a heap object, and drives a victim to it via a link, ad, or compromised site. When the victim's pre-patch Chrome renders the page, the use-after-free is triggered and the attacker executes arbitrary code within the browser sandbox. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Stable channel; on managed fleets, force the browser relaunch so the update actually applies, since Chrome stages updates but requires a restart. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Initiate inventory of Chrome versions across all managed desktops and identify systems running versions prior to 150.0.7871.47. …
