Network delivery requires victim page visit (UI:R); Scope:Changed reflects cross-origin escape; C:L/I:L assigned for partial per-origin session exposure with no availability impact.
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 CSS 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 prior to 151.0.7922.72 enables remote attackers to inject arbitrary scripts or HTML across origin boundaries by luring a victim to a crafted HTML page that exploits an inappropriate CSS implementation. Because this is a UXSS class vulnerability - not ordinary reflected or stored XSS - exploitation bypasses the browser's same-origin policy entirely, potentially exposing authenticated sessions, cookies, and DOM content from any tab open in the browser. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to navigate to an attacker-controlled or attacker-influenced HTML page using any desktop Chrome version prior to 151.0.7922.72. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.1 Medium score with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N reflects low attack complexity, no required privileges, and network reachability - with user interaction (visiting a crafted page) as the sole gatekeeping condition. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page embedding a specially constructed CSS rule or stylesheet that triggers Chrome's flawed implementation, then distributes the link via phishing email or malvertising. When a target running a vulnerable Chrome version visits the page, the CSS flaw causes Chrome to execute attacker-controlled scripts in cross-origin contexts, allowing the attacker to silently read session cookies or tokens from authenticated tabs - such as webmail or corporate SSO portals - open in the same browser. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later immediately; this is the vendor-released patch per the 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. |
