CVE-2026-17831: Insufficient validation of untrusted input in Google Chrome
Insufficient validation of untrusted input in Passwords in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
This vulnerability in Google Chrome arises from insufficient validation of untrusted input within the Passwords feature. An attacker who has already compromised the renderer process can exploit this flaw to conduct UI spoofing attacks by crafting malicious HTML pages. The CVSS score is 6.5 (medium severity) with an attack vector of network, low attack complexity, no privileges required, user interaction required, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact. The issue affects Chrome versions prior to 151.0.7922.72.
Potential Impact
The vulnerability allows an attacker with control over the renderer process to perform UI spoofing, potentially misleading users by displaying fraudulent user interface elements. There is no direct confidentiality or availability impact. The integrity of the user interface can be compromised, which may facilitate phishing or social engineering attacks.
Mitigation Recommendations
