Analysis

Impact

Google Chrome contains an input validation flaw in its WebRTC component. A maliciously crafted HTML page can exploit this flaw, allowing an attacker to execute code with the privileges of the host system. The vulnerability is classified as CWE‑20. This escalated access compromises the confidentiality, integrity, and availability of the affected machine.

Affected Systems

The vulnerability affects Google Chrome versions prior to 150.0.7871.47 on any platform that includes a WebRTC implementation. Systems running an insecure version of Chrome are at risk.

Risk and Exploitability

The EPSS score is <1% and the vulnerability is not listed in the CISA KEV catalog. The CVSS score is 8.8, indicating high severity. The likely attack vector is remote via a crafted HTML page, inferred from the description. Privilege escalation could be achieved without user interaction beyond opening the malicious page.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update Google Chrome to version 150.0.7871.47 or later, channel release
If an update is not immediately available, disable WebRTC in Chrome by setting the Group Policy 'WebRTCIPHandlingPolicy' to 'disable_all' or enabling the 'disable-webrtc' flag in chrome://flags
If disabling WebRTC is not feasible, configure a firewall rule to block outbound UDP/TCP traffic to known WebRTC STUN/TURN servers used by Chrome
