Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim is using Google Chrome Mobile on iOS - specifically a version prior to 152.0.7977.65 - and is running on an Apple iOS device. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The overall real-world risk is low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page embedding input designed to trigger Chrome's validation flaw and hosts it on an attacker-controlled site or sends a link via phishing. A victim using Chrome on iOS visits the page, causing Chrome to misprocess the input and bypass an iOS system access restriction, potentially granting the attacker's page unauthorized low-level permissions or enabling an action that should be blocked by platform controls. … |
| Remediation | Update Google Chrome on iOS to version 152.0.7977.65 or later, available through the Apple App Store. … Detailed patch versions, workarounds, and compensating controls in full report. |
