CVE-2026-7996Network attack vector

UI spoofing via SSL input validation failure

Published May 6, 2026 · Updated May 6, 2026

Insufficient input validation in Google Chrome before 148.0.7778.96 allows remote attackers to spoof browser UI via crafted HTML. The SSL component accepts untrusted renderer-supplied input without sufficient validation, but the restricted Chromium issue leaves the faulty operation undisclosed. Exploitation requires a compromised renderer and user interaction, and the reported consequence is deceptive browser UI rather than arbitrary code execution.
