chromium-browser: chromium-browser: Insufficient validation of untrusted input in Media

Published Jul 14, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

Insufficient validation of untrusted input in Media in Google Chrome on Windows prior to 150.0.7871.125 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)

Analysis

Technical impact

Google Chrome for Windows prior to 150.0.7871.125 has insufficient validation of media input in the renderer process. This flaw, tied to CWE-125 and CWE-20, allows a remote attacker who has already compromised the renderer process to read potentially sensitive information from the renderer process memory. Chromium security reviewers consider the flaw high severity.

Affected Systems

The vulnerability affects Google Chrome browsers running on Windows operating systems that use versions earlier than 150.0.7871.125. The affected product is Chrome for Windows; no other vendors or platforms are mentioned.

Risk and Exploitability

The CVSS score of 5.3 classifies the flaw as medium severity, while the EPSS score of less than 1% indicates a low probability of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires the attacker to first gain control of the renderer process, as stated in the CVE description. Consequently, the overall risk remains moderate to low.

Affected Products

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

OpenCVE Recommended Actions

Upgrade Google Chrome to version 150.0.7871.125 or later on all Windows systems.
