S:C chosen over vendor's S:U because UXSS by definition crosses origin boundaries, affecting security scope beyond the loaded page; C/I remain L given described 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 Extensions 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 Extensions subsystem, affecting all versions prior to 151.0.7922.72, allows a remote unauthenticated attacker to inject arbitrary scripts or HTML into the browser context by luring a user to a crafted HTML page. The inappropriate implementation in the Extensions component bypasses Chrome's normal script isolation boundaries, potentially enabling cross-origin script execution characteristic of UXSS class flaws. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must deliver a specially crafted HTML page to a victim running Google Chrome prior to 151.0.7922.72 (CVSS PR:N confirms no attacker authentication is required). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 5.4 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N reflects a moderate base risk: network-reachable, low complexity, no privileges required, but dependent on user interaction and scored with unchanged scope. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing malicious content designed to trigger the inappropriate extension handling behavior in Chrome's Extensions subsystem. A targeted user is socially engineered into visiting the page - via phishing link, malvertising, or embedded iframe - causing Chrome to process the page through the vulnerable extension code path and execute attacker-controlled scripts or inject HTML in the browser context. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, the vendor-confirmed patched release documented at the Chrome Releases stable channel advisory (chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
