CVE-2026-5895 Overview
CVE-2026-5895 is a security UI vulnerability affecting Google Chrome on iOS devices. The flaw exists in the Omnibox component (URL bar) and allows remote attackers to spoof the contents of the URL bar through crafted domain names. This type of vulnerability can be leveraged in phishing attacks where users are misled about the legitimacy of websites they are visiting.
Critical Impact
Remote attackers can manipulate the displayed URL in Chrome's Omnibox on iOS devices, potentially deceiving users into believing they are visiting legitimate websites when they are actually on malicious domains.
Affected Products
- Google Chrome on iOS prior to version 147.0.7727.55

Technical Details for CVE-2026-5895
Vulnerability Analysis
This vulnerability falls under the User Interface Confusion category, specifically affecting how Google Chrome on iOS renders and displays domain names in the Omnibox (URL bar). The Omnibox serves as a critical security indicator for users, displaying the current website's URL to help users verify they are on legitimate sites.
The flaw enables attackers to craft domain names that, when rendered in the Omnibox, appear differently than their actual value. This creates an opportunity for social engineering attacks where users may be tricked into believing they are visiting trusted domains when they are actually on attacker-controlled sites.
Chromium has categorized this as a Low severity security issue, indicating limited direct technical impact but acknowledging the potential for user deception. The attack requires user interaction—specifically, the victim must navigate to an attacker-controlled website with the crafted domain name.
Root Cause
The root cause of this vulnerability lies in improper handling of certain domain name characters or sequences within Chrome's iOS Omnibox rendering logic. The security UI fails to accurately represent the true destination URL, allowing visually similar or deceptive domain representations to be displayed to users.
Attack Vector
The attack vector for CVE-2026-5895 involves a remote attacker hosting a website with a specially crafted domain name. When an iOS user running a vulnerable version of Chrome navigates to this site (typically via a phishing link), the Omnibox displays a spoofed URL that may appear to be a legitimate domain.
A typical attack scenario would involve:
- Attacker registers a domain with specially crafted characters
- Attacker sends phishing links to potential victims
- Victim clicks the link on their iOS device using Chrome
- The Omnibox displays a misleading URL, increasing the likelihood that the victim trusts the malicious site
Detection Methods for CVE-2026-5895
Indicators of Compromise
- Users reporting suspicious website behavior despite URL appearing legitimate
- Browser crash reports or anomalies related to Omnibox rendering on iOS devices
- Increased reports of phishing attacks targeting iOS Chrome users
Detection Strategies
- Monitor for phishing campaigns leveraging IDN homograph attacks or similar URL spoofing techniques
- Implement URL reputation services to flag known malicious domains using this technique
- Review user reports of URL display discrepancies in Chrome on iOS
Monitoring Recommendations
- Enable Chrome browser telemetry to detect rendering anomalies
- Monitor security feeds for reports of active exploitation of this vulnerability
- Track phishing campaigns that may be leveraging URL spoofing techniques targeting iOS users
How to Mitigate CVE-2026-5895
Immediate Actions Required
- Update Google Chrome on iOS devices to version 147.0.7727.55 or later
- Educate users about verifying URLs carefully, especially when clicking links from untrusted sources
- Consider implementing URL filtering and web security gateways to block known malicious domains
Patch Information
Google has addressed this vulnerability in Chrome version 147.0.7727.55 for iOS. Organizations and users should update to this version or later to remediate the vulnerability.
For additional information, refer to the Google Chrome Stable Update announcement and the Chromium Issue Tracker entry.
Workarounds
- Implement mobile device management (MDM) policies to enforce browser updates
- Use enterprise URL filtering to block access to suspicious or newly registered domains
- Train users to manually verify URLs by examining the full domain before entering sensitive information
- Consider using bookmark-based navigation for sensitive sites rather than clicking links
