DescriptionCVE.org

Insufficient policy enforcement in Network in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to bypass content security policy via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Content Security Policy bypass in Google Chrome prior to 150.0.7871.47 allows a remote attacker to circumvent network-level policy enforcement by delivering a crafted HTML page to a victim. The Chrome security team internally rated this as Low severity, consistent with the CVSS 4.3 score and an impact limited to integrity (I:L) with no confidentiality or availability consequences. No public exploit code or active exploitation has been identified; EPSS places this in the 8th percentile of exploitation likelihood.

Technical ContextAI

The vulnerability resides in Chrome's Network component, which is responsible for enforcing Content Security Policy (CSP) directives - a browser-level protection mechanism that restricts which external resources (scripts, styles, frames, etc.) a page may load. CWE-693 (Protection Mechanism Failure) captures the root cause: Chrome's network layer fails to correctly apply or validate CSP rules under conditions achievable via a crafted HTML page. Affected CPE corresponds to Google Chrome versions prior to 150.0.7871.47 across desktop platforms. CSP bypasses in browsers can enable cross-site scripting amplification or unauthorized resource loading that policy authors explicitly intended to block.

RemediationAI

Update Google Chrome to version 150.0.7871.47 or later, available via Chrome's built-in update mechanism or directly from the vendor advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Enterprise administrators should push the update through fleet management tooling (e.g., Google Admin Console, WSUS, Intune) to ensure prompt deployment across managed endpoints. No vendor-documented workaround is available for this specific CSP enforcement flaw; blocking access to attacker-controlled HTML pages via web proxy URL filtering could reduce exposure in high-sensitivity environments, but this is impractical as a general mitigation. Chromium-based browsers (Edge, Brave, etc.) derived from an affected codebase may require separate upstream updates from their respective vendors.
