Google Chrome CredentialProvider Memory Corruption Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.6)

CVE-2026-113283

The vulnerability exists within the CredentialProvider component of Google Chrome on Windows. While triggered via a crafted HTML page, this component is not a public-facing network service. Typical browser usage involves visiting websites, but the specific interaction required with this local credential management component makes public internet exposure uncommon in standard deployments.

Frequently asked questions

What is the Google Chrome CredentialProvider?

CredentialProvider is a specific component within the Windows version of Google Chrome. It handles the interface for managing saved user credentials and authentication data. It functions as a bridge between the browser's stored secrets and the Windows operating system's authentication processes.

What does memory corruption mean in CVE-2026-113283?

This vulnerability is classified as CWE-119, which refers to improper restriction of operations within memory boundaries. In this case, the CredentialProvider fails to properly handle data, allowing an attacker to overwrite sensitive memory areas. This weakness can be abused to bypass the browser's security sandbox and execute unauthorized code on the host machine.

How is this vulnerability triggered?

An attacker must entice a user to visit a specially crafted HTML page while using an affected version of Chrome on Windows. Simply having the browser installed does not trigger the bug; the specific malicious interaction through a web page is necessary to initiate the memory corruption process.

Is my system at risk for CVE-2026-113283?

According to Halo Surface Signal, this risk is labeled as Unlikely for most users. While triggered by a web page, the vulnerability resides in a local credential management component that is not typically exposed as a public-facing network service. The threat level depends on how your environment uses Chrome's credential integration features on Windows.

Do I need to update my software to address this?

Yes, you should verify your current Chrome version. Since this issue involves arbitrary code execution, the primary response is to update to version 156.0.8078.47 or later. After updating, ensure your team confirms the deployment scope to verify that all systems running the affected CredentialProvider component are protected.
