Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) Google Chrome for Android prior to version 153.0.8010.36 to be installed on the victim's Android device; (2) a co-installed application that the attacker controls or has compromised, capable of opening Chrome CustomTabs and influencing the displayed URL; and (3) the victim to view or interact with the spoofed CustomTab session. … 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:N/S:U/C:L/I:N/A:L, score 4.8) reflects elevated attack complexity due to the co-installed app prerequisite (AC:H), which is the primary practical barrier to exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome for Android to version 153.0.8010.36 or later via the Google Play Store or Chrome's built-in update menu (Settings > About Chrome). … Detailed patch versions, workarounds, and compensating controls in full report. |
