Insufficient validation of untrusted input in Chrome for iOS in Google Chrome on iOS prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability in Google Chrome on iOS versions prior to 150.0.7871.47 allows remote attackers to perform UXSS attacks by exploiting insufficient validation of untrusted input. The attack requires user interaction through specific UI gestures and a crafted HTML page. The CVSS vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity, with no impact on availability.
Potential Impact
Successful exploitation could allow an attacker to inject arbitrary scripts or HTML into the browser context, potentially leading to cross-site scripting attacks that affect the confidentiality and integrity of user data within the browser. The impact is limited to the browser environment and requires user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users and administrators should monitor the official Google Chrome release notes and update to version 150.0.7871.47 or later once confirmed. Until then, caution is advised when interacting with untrusted web content, especially on iOS devices running affected Chrome versions.
