CVE-2026-17908 is a vulnerability in the printing functionality of Google Chrome on Windows versions before 151.0.7922.72. It arises from insufficient validation of untrusted input, enabling a remote attacker with control over the renderer process to potentially perform a sandbox escape via a crafted HTML page. This could undermine the browser's security isolation mechanisms. The vulnerability is classified under CWE-20 (Improper Input Validation). No CVSS score is provided, and no known exploits in the wild have been reported.

The vulnerability could allow an attacker who has already compromised the renderer process in Chrome on Windows to escape the sandbox environment, potentially increasing the attacker's privileges or capabilities on the host system. However, the Chromium security team has assessed the severity as low, indicating limited impact or difficulty in exploitation.

A fix is available in Google Chrome version 151.0.7922.72 and later. Users and administrators should update affected Chrome installations to version 151.0.7922.72 or newer to remediate this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
