Domain spoofing via improper certificate validation
Published Jul 21, 2026 · Updated Jul 21, 2026
Improper input validation in Google Chrome before 150.0.7871.182 on Linux allows man-in-the-middle attackers to spoof domains. The Certificate component accepts malicious network traffic without sufficient validation, but Google has not disclosed the specific certificate field or validation operation involved. A privileged network position controlling malicious traffic is required, and the bounded reported consequence is domain spoofing.
