Analysis

Impact

A race condition in the WebRTC component of Google Chrome on Windows allows a malicious web page to trigger a flaw that causes the browser to read and expose data belonging to a different origin. This vulnerability represents a confidentiality breach and is classified as CWE-362.

Affected Systems

Google Chrome users on Windows with a version earlier than 150.0.7871.47 are affected.

Risk and Exploitability

The CVSS score of 6.5 indicates medium severity, while the EPSS score of < 1% suggests a very low but non-zero exploitation likelihood. The vulnerability is not listed in CISA KEV. Exploitation requires a victim to visit a crafted web page that triggers the WebRTC race condition during normal browser activity, allowing the attacker to read cross-origin data from the browser’s memory. While feasible, the low EPSS indicates limited real-world spread.

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

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Upgrade Google Chrome to at least version 150.0.7871.47, which removes the WebRTC race condition.
If an upgrade is not immediately possible, disable WebRTC by setting the chrome flag chrome://flags/#enable-webrtc to Disabled or using an extension that blocks WebRTC traffic.
Ensure web applications enforce strict same-origin policies and relevant Content-Security-Policy headers to limit cross-origin data exposure.
