CVE-2026-76041 is a high-severity information disclosure vulnerability identified in Google Chrome’s Skia graphics engine. Skia is an open-source 2D graphics library that serves as the rendering engine for Chrome, handling the drawing of text, geometric shapes, and images across the browser’s user interface and web content. The vulnerability resides in how Skia processes certain graphical operations, allowing a remote attacker to potentially bypass the web origin policy.
The web origin policy is a critical security mechanism that restricts how documents or scripts loaded from one origin can interact with resources from another origin. By leaking sensitive information across origin boundaries, this vulnerability undermines the same-origin policy—a cornerstone of web security.
Exploitation occurs when a victim visits a specially crafted HTML page. The malicious page triggers an information leak within Skia, enabling the attacker to read sensitive data from other origins that should be protected. This could include cross-origin images, local file references, or other resources that violate the browser’s security model.
The vulnerability affects Google Chrome versions prior to 151.0.7922.169. Google addressed the issue with the August 18, 2026, stable channel update, releasing version 151.0.7922.169 for Windows and Linux, and 151.0.7922.170 for Mac. The Chromium security team classified this flaw with a “High” severity rating.
The vulnerability is rooted in CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. According to CISA-ADP analysis, the vulnerability has a CVSS v3.1 base score of 4.3 (Medium), with the vector string: AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N. The attack vector is network-based, requires low attack complexity, no privileges, but does require user interaction (the victim must visit a malicious page). The scope remains unchanged, with low confidentiality impact and no integrity or availability impact. Red Hat, however, assessed the vulnerability with a CVSS score of 7.4 (Important), citing a scope change (S:C) and high confidentiality impact (C:H) with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N. EPSS (Exploit Prediction Scoring System) estimates the probability of exploitation at 0.34%.

Exploit: (Educational Purposes!)
The exploitation of CVE-2026-76041 relies on a remote attacker crafting a malicious HTML page that triggers the information leak within the Skia graphics engine. When a victim visits this page, the flaw allows the attacker to potentially bypass the web origin policy and read sensitive information from other origins. The attacker must trick the user into interacting with the crafted page, as user interaction is required. The vulnerability is not automatable, meaning each attack requires active user participation. The technical impact is partial, as the leak primarily exposes confidentiality rather than enabling full system compromise.
Protection:
To protect against CVE-2026-76041, users must update Google Chrome to version 151.0.7922.169 or later. For Linux users, the patched version is 151.0.7922.169; for Windows and Mac users, version 151.0.7922.170 addresses the flaw. As a temporary workaround, users should avoid visiting untrusted websites or opening suspicious HTML files. Additional protective measures include disabling JavaScript or using privacy-focused browser extensions. Users should exercise caution when browsing and only access reputable sources.
Impact:
Successful exploitation of CVE-2026-76041 could lead to unauthorized access to sensitive information across different web origins. An attacker could potentially read cross-origin data that should be protected by the browser’s security model, compromising user privacy and data confidentiality. The vulnerability affects Google Chrome prior to 151.0.7922.169 and extends to Chromium-based browsers, including those on Debian and other Linux distributions. The flaw has been addressed in the August 18, 2026, security update. Users running unpatched versions remain at risk of information disclosure attacks that could expose sensitive browsing data across origins.
