CVE-2023-0704Network attack vector

Same-origin and proxy policy bypass

Published Feb 7, 2023 · Updated Mar 20, 2025

Insufficient policy enforcement in Google Chrome DevTools before 110.0.5481.77 allows remote attackers to bypass same-origin and proxy controls. The public advisory does not disclose the exact DevTools locus or the incorrect operation that mishandles the crafted HTML page. A user must open the crafted page; successful exploitation circumvents browser-enforced request boundaries without reported data disclosure or service interruption.
