Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be on an Android device running Google Chrome prior to version 152.0.7977.65 and to open a crafted HTML page within a CustomTabs-enabled application - this is the key limiting condition, as the spoofing only manifests in the CustomTabs context, not in standalone Chrome browser tabs. … 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:N/I:L/A:N) reflects a low-complexity, network-reachable flaw requiring only user interaction, with a narrow impact limited to integrity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that exploits the CustomTabs rendering flaw to display a trusted domain (e.g., a bank or enterprise SSO portal) in the address bar while serving attacker-controlled content. A victim receives a link via email, SMS, or an in-app notification; upon opening it in an Android app using CustomTabs, the address bar shows a spoofed legitimate URL, inducing the victim to submit credentials or approve actions. … |
| Remediation | Vendor-released patch: Chrome for Android 152.0.7977.65. … Detailed patch versions, workarounds, and compensating controls in full report. |
