Inappropriate implementation in CSS in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Cross-origin data leak in Google Chrome's CSS implementation (versions prior to 150.0.7871.47) enables remote attackers to exfiltrate sensitive data from other origins when a victim visits a specially crafted HTML page. The vulnerability stems from inappropriate CSS handling that creates a side-channel bypassing same-origin policy protections, resulting in high-confidentiality-impact information disclosure with no integrity or availability consequences. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit an attacker-controlled or compromised web page using a vulnerable Chrome version (prior to 150.0.7871.47), satisfying the UI:R condition in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) reflects network-reachable, zero-authentication exploitation with high confidentiality impact, which appears aggressive relative to corroborating signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing CSS specifically engineered to exploit the inappropriate implementation in Chrome's CSS engine, creating a side-channel that probes resources from another origin the victim is authenticated to. When a victim using Chrome prior to 150.0.7871.47 visits this page - lured via phishing, malvertising, or a compromised site - the malicious CSS leaks cross-origin data such as authentication state or page content back to the attacker. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, as confirmed by Google's stable channel release advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
