Mozilla Firefox for iOS Right-to-Left Domain Rendering Vulnerability

A vulnerability in Firefox for iOS has been identified, where the link preview feature incorrectly displayed right-to-left (RTL) and internationalized domain names (IDNs). This flaw allowed a crafted RTL hostname to visually manipulate the domain presentation, making attacker-controlled sites appear as trusted sources. The issue affects Firefox for iOS versions prior to 151.1.

Impact

Exploitation of this vulnerability could lead to phishing attacks, as it allows malicious websites to be misrepresented as legitimate by manipulating how their URLs are displayed.

Remediation

Users can update to Firefox for iOS version 151.1 to address this vulnerability.
