Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Side-channel exploitation requires controlled timing conditions (AC:H); leaking another origin's data implies scope change (S:C) with partial confidentiality loss (C:L), not full disclosure.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim actively visit an attacker-controlled HTML page using a desktop Chrome version prior to 150.0.7871.47 - passive or drive-by exploitation without user navigation is not possible (UI:R confirmed by CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) implies a medium-severity, broadly accessible, unauthenticated attack with high confidentiality impact - which on paper sounds alarming. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a malicious website and embeds a crafted HTML page containing CSS designed to trigger differential rendering timing or style-resolution behavior in Chrome's layout engine. A victim using a vulnerable Chrome version visits the page - perhaps via a phishing link - causing Chrome to process the malicious CSS in a way that leaks timing or state information about cross-origin resources the victim has loaded in other tabs or authenticated sessions. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later immediately via the browser menu (Help > About Google Chrome) or via enterprise deployment tooling; the vendor advisory is at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
