CVE-2026-2378Network attack vector

User-assisted address bar spoofing

Published Mar 20, 2026 · Updated Mar 20, 2026

Address bar spoofing in Arc Search for Android before 1.12.7 allows remote attackers to misrepresent attacker-controlled content. The vendor states that the address bar can show a domain different from the rendered page, but it does not disclose the internal rendering or navigation operation that causes the mismatch. Exploitation requires crafted web content and user interaction, enabling phishing through a false trusted-domain indicator without reported code execution or service interruption.
