A serious security flaw has been discovered in Google Chrome, originating from an error in the improper input checks in the graphics component of Chromium, namely the ANGLE and GPU. This vulnerability allows the attacker to bypass the browser’s sandbox mechanism, opening up further access to the victim system.

The vulnerability is classified under CWE 20, which involves improper handling of the input. An attacker simply needs to lure his victim to access a specially designed HTML page that can be exploited. No downloads or install is required, but a click on a malicious website can break the sandbox’s protective coating, causing the risk to spread quickly.

As a sandbox escape vulnerability, this problem is particularly serious because the sandbox is the primary defense line that prevents malicious code from the web accessing system resources. The danger is greater when the weakness is in ANGLE, the component responsible for transferring graphical commands from OpenGL ES to native APIs such as Direct3D or Vulkan. This is an area that often requires high privilege and the ability to interact directly with hardware, making mining much more dangerous.

Technically, the vulnerability can be exploited through malicious shaders or buffers in WebGL content, which leak data, or execute code that is outside the sandbox range. When ANGLE does not properly process input values, attackers can overwrite memory and execute code at the graphics driver level. If combined with another privilege escalation breach, the sandbox escape can pave the way for an attacker to take control of the entire system.

Not only affected Chrome, the vulnerability also threatened the entire browser ecosystem using the Chromium kernel such as Microsoft Edge, Opera, and many other popular browsers. Sharing a core platform means that a single vulnerability can impact millions of users across multiple devices and brands.

CISA and other cybersecurity agencies have issued emergency warnings, recommending that users and organizations update their browsers as soon as possible and implement vendor – mandated mitigation measures. In cases where it is not possible to safely protect the system, organizations are advised to suspend using the affected browser until an official patch is available.

The breach was officially noted on July 22, 2025, with a processing time limit until August 1. This timeline reflects the degree of urgency and risk that security professionals assess. While there is no indication of exploitation in ransomware campaigns, the ability to bypass the sandbox makes the vulnerability an attractive target for cybercriminals. Users should actively update their browsers and closely monitor warnings from developers.
