AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N
Network-exploitable via crafted page (AV:N), but preload timing conditions require high complexity (AC:H); user must actively visit attacker page (UI:R); impact is solely partial cross-origin information disclosure with no write or availability consequence (C:L/I:N/A:N).

Improper resource exposure in Preload in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to bypass site isolation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Improper resource exposure in Google Chrome's Preload mechanism prior to version 152.0.7977.65 enables remote attackers to bypass Site Isolation by luring a user to a crafted HTML page. The flaw (CWE-668) allows cross-origin resource data to leak across security boundaries, undermining Chrome's core renderer isolation architecture and potentially exposing sensitive information from other origins loaded in the browser. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit a crafted HTML page under the attacker's control, satisfying the UI:R requirement - delivery via phishing, malvertising, or a compromised website is necessary. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 3.1 score of 3.1 (Low) accurately reflects the constrained real-world impact: the network attack vector (AV:N) is offset by high complexity (AC:H), mandatory user interaction (UI:R), unchanged scope (S:U), and only low confidentiality impact (C:L) with no integrity or availability consequences. … 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 | The primary fix is to update Google Chrome to version 152.0.7977.65 or later; this is a vendor-released patch documented in Google'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. |
