CVE-2026-13901 - Vulnerability Details

Description

Insufficient policy enforcement in Serial in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

Published: 2026-06-30

Score: 9.6 Critical

EPSS: < 1% Very Low

Analysis

Impact

Insufficient policy enforcement in Chrome’s Serial API before version 150.0.7871.47 lets a remote attacker who has already compromised the renderer process escape from the sandbox and could execute arbitrary code. The flaw is caused by improper input validation (CWE‑20) and inadequate permission checks (CWE‑602).

Affected Systems

All users running Google Chrome Desktop stable on any operating system with a version lower than 150.0.7871.47 are affected; the vulnerability is confined to the Serial API implementation.

Risk and Exploitability

The CVSS score of 9.6 indicates a high severity, but the EPSS score of less than 1% suggests that exploitation is unlikely under current conditions. The attack requires delivering crafted HTML to a compromised renderer process – for example via malicious web content – and then abusing the Serial API to escape the sandbox. The vulnerability is not listed in the CISA KEV catalog, so no known active exploits are publicly documented.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Upgrade to Chrome 150.0.7871.47 or later, which addresses the Serial API policy enforcement flaw.
If an update cannot be performed immediately, block Serial API access by disabling the feature through Chrome policy or flag settings.
Restrict system‑level access to serial device drivers so that even a compromised renderer process cannot open serial ports.
