Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim running Google Chrome prior to 152.0.7977.65 to visit a crafted HTML page under attacker control - user interaction (UI:R) is a hard prerequisite and cannot be bypassed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 is driven by a network-reachable (AV:N), low-complexity (AC:L) attack vector requiring no privileges (PR:N) but mandating user interaction (UI:R), with high confidentiality impact (C:H) and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a malicious ServiceWorker on a crafted web page and lures a victim to visit it via phishing or a malicious redirect. Upon page load, the ServiceWorker exploits the information leak to read sensitive cross-origin data - such as authentication tokens, cached API responses, or cookies - and exfiltrates them to an attacker-controlled endpoint. … |
| Remediation | Vendor-released patch: Chrome 152.0.7977.65. … Detailed patch versions, workarounds, and compensating controls in full report. |
