Analysis

Impact

Insufficient validation of untrusted input in Chrome's Chromoting component on Windows permits a local attacker to supply a malicious file and potentially escape the browser sandbox. This vulnerability is classified as CWE-20 and could allow an attacker to move from a restricted browser process into the wider Windows environment, creating the risk of full system compromise.

Affected Systems

Google Chrome for Windows, any revision before 150.0.7871.47. The flaw specifically targets the Chromoting feature.

Risk and Exploitability

Chromium rates the issue as high with a CVSS score of 8.6. The EPSS score is below 1%, indicating a very low but non‑zero likelihood of exploitation, and it is not listed in CISA’s KEV catalog. The vulnerability requires a local attacker to deliver a malicious file that the Chromoting component processes; it is inferred that the attacker must have the ability to open or interact with such a file in actively running.

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