chromium-browser: Insufficient validation of untrusted input in Media

Published Jun 4, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
Description
Insufficient validation of untrusted input in Media in Google Chrome on Windows prior to 149.0.7827.53 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)

Analysis

AI-generated

Technical impact

Insufficient validation of untrusted input in the Media module of Google Chrome on Windows permits a remote attacker who has already compromised the renderer process to craft an HTML page that may escape the browser sandbox. The vulnerability arises from inadequate input validation (CWE‑20) and weaknesses in media handling that allow the sandbox to be bypassed (CWE‑1286). No additional capabilities beyond breaking out of the sandbox are specified in the description.

Affected Systems

Google Chrome for Windows users running any version before 149.0.7827.53 are affected. The issue applies to the Windows rendering engine and media handling components in these releases.

Risk and Exploitability

The CVSS score of 8.8 classifies the issue as high severity, while the EPSS score of < 1% indicates a low but non‑zero likelihood of exploitation. The vulnerability is not listed in the CISA KEV catalog and no public exploits are known. With the requirement that the attacker already control the renderer process, remediation of the flaw remains a high priority due to the potential for a sandbox escape.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 149.0.7827.53 or later.
  • If an immediate upgrade is not possible, configure enterprise policies or extensions to restrict or disable media content in untrusted HTML pages.
  • Monitor renderer process activity for anomalous behavior that could indicate a sandbox escape attempt.
