Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome prior to version 152.0.7977.65 on a desktop platform with WebXR API support available. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) accurately reflects a meaningful but constrained risk profile: the attack is network-reachable and requires no authentication, but mandatory user interaction (UI:R via social engineering) and a limited confidentiality-only impact (C:L) cap the real-world severity. … 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 WebXR session APIs in a specific sequence designed to trigger a read of uninitialized memory within Chrome's WebXR implementation. The attacker distributes the link via phishing email or malicious advertisement to lure a victim running a pre-patch Chrome version into visiting the page. … |
| Remediation | The primary fix is to update Google Chrome to version 152.0.7977.65 or later, which resolves the uninitialized resource in WebXR. … Detailed patch versions, workarounds, and compensating controls in full report. |
