Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
AC:H reflects the mandatory prior renderer compromise; S:C captures site isolation bypass across origins; C:H for cross-origin data leak; no integrity or availability impact.

Information leak in Navigation in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to bypass site isolation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Navigation component information leak in Google Chrome prior to 153.0.8010.36 enables an attacker who has already compromised the renderer process to bypass site isolation and exfiltrate cross-origin data via a crafted HTML page. This is a second-stage exploit component: it cannot be chained without a prior renderer compromise, which significantly elevates the effective attack complexity despite the AV:N/AC:L CVSS surface reading. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already achieved code execution within a Chrome renderer process - a significant prerequisite that demands a separate, chained renderer exploit. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS scores this at 6.5 (Medium) with AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, but the vector materially understates the actual attack complexity: the description explicitly requires a prior renderer compromise, which implies a full preceding exploit chain - something CVSS AC:L does not capture. … 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 153.0.8010.36 or later via Chrome's built-in auto-update mechanism or by downloading directly from the stable channel. … Detailed patch versions, workarounds, and compensating controls in full report. |
