Network-delivered UXSS requires only victim page visit (PR:N, UI:R); cross-origin script injection justifies S:C; C:L/I:L reflect limited but real cross-origin data access and manipulation.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Inappropriate implementation in Network in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Universal Cross-Site Scripting (UXSS) in Google Chrome's Network component allows remote attackers to inject arbitrary scripts or HTML across same-origin policy boundaries via a crafted HTML page, affecting all Chrome versions prior to 151.0.7922.72. Unlike application-level XSS, UXSS exploits a flaw in the browser engine itself, enabling cross-origin script execution that bypasses website-level security controls. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively navigate to or load attacker-controlled HTML content in an unpatched Chrome browser prior to version 151.0.7922.72 - this is the UI:R (user interaction required) condition encoded in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.1 Medium score reflects a network-accessible, no-privilege, user-interaction-required attack with limited confidentiality and integrity impact but a scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that triggers the inappropriate network handling in Chrome, causing it to inject attacker-controlled script into the context of a different origin - for example, a banking or identity provider site already open in the victim's browser. The victim is lured to the attacker's page via phishing, a malicious ad, or a compromised site, and upon page load the UXSS payload executes silently, potentially harvesting session tokens or performing actions on the victim's behalf on targeted origins. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later; this is the vendor-released patch confirmed by the Chrome stable channel 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. |
