AI Analysis

Impact

The flaw arises from insufficient validation of untrusted input in the DevTools interface. A remote attacker can coerce a user into performing certain UI gestures, causing the browser to accept malicious network traffic and bypass the Same Origin Policy.

Affected Systems

Google Chrome versions prior to 149.0.7827.53 on all desktop platforms are vulnerable. The issue is present in the stable channel and has been noted in Chromium issue 499164652.

Risk and Exploitability

Chromium rates this vulnerability as High, with a CVSS score of 8.8 that highlights significant potential impact. The EPSS score indicates a very low but non-zero probability of exploitation (< 1%). This issue is not listed in the CISA KEV catalog. Exploitation would require social engineering to convince the user to interact with the specified gestures, and no public exploit has been confirmed.
