Inappropriate implementation in ReportingAndNEL in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's ReportingAndNEL subsystem (versions prior to 151.0.7922.72) allows a remote attacker to exfiltrate limited cross-origin information by delivering a crafted HTML page to a victim user. The flaw stems from an origin validation error (CWE-346) in the Network Error Logging and Reporting API implementation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively navigate to an attacker-controlled HTML page using Google Chrome prior to version 151.0.7922.72 - user interaction is a hard prerequisite (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N accurately reflects a network-reachable, low-complexity flaw requiring no attacker privileges but mandating user interaction - a victim must visit a crafted page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a reporting endpoint and hosts a crafted HTML page that sets NEL or Reporting-Endpoints headers referencing cross-origin resources, causing a victim's Chrome browser to process and relay cross-origin network event data to the attacker's collector. When a user visits this page in a vulnerable Chrome version, the browser's flawed origin validation allows the attacker to observe limited information about cross-origin requests or responses that should be opaque. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which contains the corrected ReportingAndNEL implementation per the vendor advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
