Network vector with no auth required, but UI:R is mandatory due to social engineering; only partial cross-origin confidentiality loss applies, so C:L with I:N and A:N.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running Google Chrome prior to version 152.0.7977.65 on a desktop platform with the DeviceBoundSessionCredentials feature active (a Chrome-internal session-binding component, not a user-configurable setting). … 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:L/I:N/A:N yields a 4.3 Medium score, reflecting a network-reachable but user-interaction-dependent flaw with limited confidentiality impact and no integrity or availability consequence. … 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 | Update Google Chrome to version 152.0.7977.65 or later, as detailed in the Chrome 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. |
