Severity by source
Sources disagree (Medium–Critical)AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N
UXSS by definition crosses origin boundaries warranting S:C; race condition timing and mandatory user visit retain AC:H and UI:R respectively.
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.

Race in Chrome for iOS in Google Chrome on iOS 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: High)
AnalysisAI
Universal Cross-Site Scripting (UXSS) in Google Chrome for iOS prior to 151.0.7922.72 allows a remote attacker to inject arbitrary scripts or HTML across origin boundaries by exploiting a race condition triggered through a crafted HTML page. The vulnerability requires user interaction and benefits from high attack complexity due to race-condition timing, placing real-world exploitation difficulty well above typical web vulnerabilities. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim is using Google Chrome on an iOS device running a version prior to 151.0.7922.72 - Chrome on Android, macOS, Windows, or Linux is not affected by this specific vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N) yields a score of 4.2, reflecting meaningful constraints: high attack complexity due to race-condition timing, mandatory user interaction, and limited confidentiality/integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page designed to trigger a specific race condition in Chrome for iOS's rendering or navigation pipeline. A victim is socially engineered or redirected to visit this page in Chrome for iOS, after which the race window is won by the attacker-controlled timing, allowing injection of arbitrary scripts into a cross-origin context - potentially enabling session token theft or malicious UI manipulation in a different origin loaded in the same browsing session. … |
| Remediation | Update Google Chrome for iOS to version 151.0.7922.72 or later, available through the Apple App Store. … Detailed patch versions, workarounds, and compensating controls in full report. |
