Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome in a version prior to 152.0.7977.65 on any desktop platform. … 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:H/I:N/A:N scores 6.5 (Medium), reflecting a network-accessible flaw that requires no attacker authentication but mandates victim UI interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious webpage and socially engineers a victim - for example via phishing, tech-support scam, or instructional lure - into opening Chrome DevTools on that page and performing a specific UI action such as clicking a menu item or navigating a panel. The missing authorization check in DevTools then allows the attacker-controlled page context to extract sensitive information from the browser session, such as cookies, network responses, or stored credentials visible in DevTools panels. … |
| Remediation | The primary fix is to update Google Chrome to version 152.0.7977.65 or later; Chrome's automatic update mechanism handles this for most consumer deployments. … Detailed patch versions, workarounds, and compensating controls in full report. |
