Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user actively visits a crafted HTML page in an unpatched Chrome browser prior to version 152.0.7977.65, reflected by the CVSS UI:R metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.3 Medium is consistent with the available signals: AV:N confirms network delivery, AC:L indicates no special conditions, PR:N reflects unauthenticated access, and UI:R introduces a meaningful barrier requiring victim interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that exploits the DOM information leak to bypass Chrome's Same-Origin Policy, then delivers the URL to a victim via phishing, malicious advertisement, or compromised website. Once the victim loads the page in an unpatched Chrome browser, attacker-controlled JavaScript reads cross-origin DOM content - potentially extracting session-related fragments, tokens, or other sensitive data rendered from a co-loaded trusted origin. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch per the stable channel update 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. |
