Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim use a Google Chrome version prior to 152.0.7977.65 and navigate to an attacker-controlled HTML page - user interaction (UI:R) is the primary limiting condition. … 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 describes a network-reachable, low-complexity flaw requiring no attacker privileges and only routine user interaction (visiting a page), with high confidentiality impact confined to the browser scope. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a specially crafted HTML page designed to trigger the incorrect authorization logic in Chrome's WebProtect component, then delivers a link to the target via phishing email, malvertising, or a compromised website. The victim opens the link in an unpatched Chrome browser; the crafted page bypasses WebProtect's authorization checks and reads sensitive browser-accessible information, which is returned to the attacker. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, as confirmed by the vendor's stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
