CVE-2026-8006Network attack vector

UI spoofing via undisclosed DevTools policy bypass

Published May 6, 2026 · Updated May 6, 2026

Insufficient policy enforcement in Google Chrome before 148.0.7778.96 allows attackers to perform UI spoofing via a crafted extension. Google identifies DevTools as the affected component but has not disclosed which policy check fails or how the crafted extension manipulates trusted browser UI. Exploitation requires the user to install the malicious extension, after which displayed interface content can misrepresent security-relevant information; no code execution or privilege escalation is reported.
