Avant Browser 11.7 Builds 35 and 36 allows remote attackers to spoof the address bar, via window.open with a relative URI, to show an arbitrary URL on the web site visited by the victim, as demonstrated by a visit to an attacker-controlled web page, which triggers a spoofed login form for the site containing that page. NOTE: a related attack was reported in which an arbitrary file: URL is shown.

Security readout for executives and security teams

This flaw lets a malicious web page make Avant Browser show a misleading address bar, potentially making a fake login page appear tied to a trusted site. The main business risk is credential theft through phishing, not direct system takeover. The source bundle does not provide CVSS severity or patch details. Exposure is likely limited to users or managed endpoints still running Avant Browser 11.7 builds 35 or 36. Modern browser fleets are unlikely to be affected unless legacy software remains installed or used for compatibility workflows. Prioritize remediation if any legacy Avant Browser use remains, especially on systems accessing email, identity, banking, customer portals, or administrative consoles. If the browser is absent from the fleet, record the finding as not applicable with evidence. Mitigation focus: Inventory endpoints for Avant Browser 11.7 builds 35 and 36.; Remove or replace legacy Avant Browser installations where possible.; Check vendor or archival guidance for fixed builds before relying on updates..
