Vulnerability AssessmentAI
| Exploitation | User interaction is required: the victim must actively visit a crafted HTML page, per CVSS UI:R. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N places this as a remotely exploitable, low-complexity, unauthenticated flaw with high confidentiality impact but requiring user interaction - a common profile for browser-based information disclosure bugs. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious website containing specially crafted CSS that triggers the information disclosure when rendered by Chrome. The attacker distributes a link via phishing email or malicious advertisement; when the victim clicks and the page loads, Chrome's CSS engine leaks sensitive information - potentially cross-origin data or browser state - back to the attacker-controlled page. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later via the stable channel update documented at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
