CVE-2026-106226 is an improper input validation vulnerability in Google Chrome's Compositing component affecting versions before 155.0.8059.39. A remote attacker who has already compromised the renderer process can use a crafted HTML page to spoof the browser's address bar. The vulnerability enables browser-interface deception; it does not itself establish the prerequisite renderer compromise.
