Insufficient validation of untrusted input in New Tab Page in Google Chrome prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's New Tab Page (NTP) component prior to version 149.0.7827.103 enables an unauthenticated remote attacker - who has already achieved renderer process compromise - to exfiltrate cross-origin data via a crafted HTML page. The vulnerability stems from insufficient input validation in the NTP, exploitable only as a second-stage attack chained after a separate renderer exploit. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two distinct conditions to be met simultaneously. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS score of 3.1 (Low) is internally consistent with the attack requirements and impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already exploited a separate Chrome renderer vulnerability to achieve renderer process compromise directs a victim user to a crafted HTML page. The malicious page triggers the insufficient input validation flaw in the New Tab Page, causing the renderer to leak cross-origin data (such as content from a page loaded in another tab or origin) back to the attacker. … |
| Remediation | The primary remediation is upgrading Google Chrome to version 149.0.7827.103 or later, as confirmed by the vendor's Stable Channel Update advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
