DescriptionCVE.org

Insufficient policy enforcement in Browser 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: Low)

AnalysisAI

Sandbox escape in Google Chrome desktop versions prior to 150.0.7871.47 lets an attacker who has already compromised the renderer process break out of the browser sandbox and gain code execution on the host via a crafted HTML page. The flaw stems from insufficient policy enforcement in the browser process (CWE-20) and, while carrying a high CVSS base score of 9.6 due to the scope change, was rated only Low severity by Chromium because it is not independently exploitable. No public exploit has been identified and EPSS probability is very low (0.17%, 7th percentile).

Technical ContextAI

The vulnerability lives in Chrome's multi-process security architecture, where untrusted web content is rendered inside a low-privilege, sandboxed renderer process that must broker all privileged operations through the higher-privilege browser process. CWE-20 (Improper Input Validation) here manifests as insufficient policy enforcement in that browser process: it fails to adequately validate or constrain requests coming from a renderer, so a renderer that is already under attacker control can coax the browser process into actions that cross the sandbox boundary. The affected component is the desktop Chrome/Chromium browser (Windows, macOS, Linux Stable channel) built on the Chromium engine; the fix landed in the Stable channel release 150.0.7871.47 tracked in Chromium issue 513271007.

RemediationAI

Vendor-released patch: 150.0.7871.47 - upgrade Google Chrome to 150.0.7871.47 or later on Windows, macOS, and Linux, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. In most environments Chrome's built-in auto-update applies this automatically; confirm by opening chrome://settings/help and restarting the browser to force the update to take effect, and in managed fleets push the updated version through your MDM/Group Policy or the enterprise update infrastructure. Because exploitation requires a pre-existing renderer compromise, interim compensating controls that harden the renderer boundary are relevant: keep Site Isolation enabled (it is on by default and separates sites into distinct renderer processes), and for high-risk users consider enabling Chrome's stricter sandboxing/enhanced protection settings - with the trade-off of occasional compatibility friction on legacy sites. Operators of Chromium-based browsers should apply the corresponding rebased build from their respective vendors.
