Network-delivered via crafted page (AV:N/AC:L); victim must visit it (UI:R/PR:N); SOP bypass yields high integrity impact (I:H) with no confidentiality or availability consequence and no scope change.
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.

Insufficient policy enforcement in WebXR in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to bypass same origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Same-origin policy bypass in Google Chrome's WebXR subsystem prior to 151.0.7922.72 allows a remote attacker to violate cross-origin integrity boundaries by luring a victim to a crafted HTML page. The flaw arises from insufficient policy enforcement (CWE-346: Origin Validation Error) in the WebXR API, enabling cross-origin write or manipulation operations that Chrome's SOP should prevent. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit a crafted HTML page using a vulnerable version of Google Chrome (prior to 151.0.7922.72), confirmed by the CVSS UI:R metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) characterizes a network-reachable, low-complexity attack that requires no attacker privileges but does require the victim to interact with a crafted page (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that invokes the WebXR API in a manner that triggers the origin validation failure, then delivers the page URL to a victim via phishing email or compromised advertisement. When the victim opens the link in a vulnerable version of Chrome, the attacker's script bypasses the same-origin policy and performs cross-origin write or manipulation operations against another origin's content or state. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which is confirmed by vendor advisory to contain the fix for this WebXR policy enforcement flaw (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
