Google has released a Google Chrome security update to address a high severity security vulnerability in WebView, a core component used to display web content across browsers and applications. The updates, Chrome versions 143.0.7499.192 and 143.0.7499.193, resolve a flaw that could allow attackers to bypass security controls and carry out unauthorized actions on affected systems.
The vulnerability, tracked as CVE 2026 0628, is tied to insufficient policy enforcement within the WebView tag. WebView plays a central role in how Chrome and many Android applications render web content. As a result, the issue raised concerns among security professionals due to its potential reach across devices and platforms.
WebView Weakness Expands Attack Surface
Security researchers noted that the impact of this vulnerability extends beyond standard desktop browsing. WebView is widely embedded in Android applications to support in app browsing and content display. A weakness at this level can expose multiple applications at once, even if users are not actively using the Chrome browser.
By exploiting the flaw, attackers could circumvent protections designed to restrict script execution and block malicious content. These safeguards are essential for preventing unauthorized access to user data and system resources. If bypassed, attackers may be able to run unwanted scripts or perform actions that users did not approve.
The issue was first reported on November 23, 2025, by security researcher Gal Weizman. This early disclosure allowed Google time to prepare and test a fix before releasing details to the public. Security experts view this approach as an effective balance between transparency and risk reduction, as it limits the chance of widespread exploitation before the Google Chrome security update was deployed.
Google confirmed that the flaw affects Chrome WebView across Windows, macOS, and Linux systems. Because WebView is also deeply integrated into the Android ecosystem, the vulnerability carries broader implications for mobile users and application developers.
Patch Rollout and Update Guidance
Google has begun rolling out the fix in stages to users worldwide as part of its ongoing Google Chrome security update efforts. The company has limited the release of detailed technical information to reduce the risk of attackers reverse engineering the vulnerability before updates are widely installed. This cautious approach is common when dealing with high impact security issues.
Users can check their Chrome version by opening the browser settings and navigating to the About Chrome section. This page automatically checks for updates and installs the latest version when available. A browser restart is required to activate the patch.
Organizations managing large numbers of devices are encouraged to prioritize the update. Delays in applying patches can significantly increase exposure, especially when vulnerabilities affect shared components used by many applications. Security teams often stress that timely patch management remains one of the most effective defenses against active threats.
The WebView vulnerability highlights ongoing challenges in modern software environments. Components designed for convenience and performance often become critical infrastructure across many products. When weaknesses emerge, they can have wide ranging effects that go beyond a single application or platform.
While Google’s response through this Google Chrome security update demonstrates a strong commitment to security maintenance, experts emphasize that updates alone are not enough. Continuous monitoring, regular patching, and user awareness remain essential parts of maintaining secure systems.
This incident serves as a reminder that widely used software components can become attractive targets for attackers. Keeping browsers and applications up to date helps reduce risk and ensures that known vulnerabilities do not become entry points for broader compromise.
