Insufficient policy enforcement in Network in Google Chrome prior to 149.0.7827.103 allowed a remote attacker who had compromised the utility process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Insufficient network policy enforcement in Google Chrome prior to 149.0.7827.103 allows a remote unauthenticated attacker - who has already compromised the browser's utility process - to leak cross-origin data by luring a victim to a crafted HTML page. The confidentiality impact is limited and scoped unchanged, yielding a CVSS base score of just 3.1 (Low). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two mandatory preconditions: (1) the attacker must have already compromised the Google Chrome utility process through a separate, independent vulnerability - this is the dominant limiting factor and makes this a chained, second-stage attack rather than a standalone exploit; and (2) user interaction is required (UI:R), meaning the victim must visit or be redirected to a crafted HTML page controlled by the attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 3.1 (Low) accurately reflects the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already achieved compromise of the Chrome utility process - through a separate, unrelated vulnerability - then serves the victim a crafted HTML page that triggers the insufficient network policy enforcement. When the victim visits the page, the compromised utility process bypasses cross-origin data isolation, allowing the attacker to exfiltrate limited cross-origin data such as response bodies or headers from other origins the victim is authenticated to. … |
| Remediation | The primary fix is upgrading Google Chrome to version 149.0.7827.103 or later, as confirmed by the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
