Remote Code Execution in ChromeDriver on Windows

IdentifiersCVE-2026-8000CWE-20· Improper Input Validation

CVE-2026-8000 is an insufficient validation of untrusted input vulnerability in ChromeDriver in Google Chrome on Windows prior to version 148.0.7778.96. According to the provided content, a remote attacker can trigger the flaw by causing a target to process a crafted HTML page. The issue is attributed to improper handling and validation of attacker-controlled input within ChromeDriver, which can lead to arbitrary code execution on the affected Windows system.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in arbitrary code execution on the affected Windows host in the context available to the vulnerable Chrome/ChromeDriver process. The provided CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates potential high impact to confidentiality, integrity, and availability, meaning an attacker may be able to run code, access or alter data, and disrupt system or application operation.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting use of vulnerable ChromeDriver instances on Windows, restricting access to systems that process untrusted web content, and preventing users or automated workflows from opening attacker-controlled HTML content. Where feasible, disable or isolate ChromeDriver-based automation on untrusted networks until the update can be applied. The provided content does not include any vendor-specific workaround beyond updating.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome/ChromeDriver on Windows to version 148.0.7778.96 or later, as the vulnerability affects versions prior to 148.0.7778.96. Apply the vendor-provided stable channel update referenced in the Chrome Releases advisory.
