Improper initialization in Network in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Chrome's Network subsystem before version 152.0.7977.65 allows remote attackers to bypass the browser's web origin policy due to improper initialization (CWE-665), exploitable via a crafted HTML page that requires user interaction. The impact is limited to partial confidentiality disclosure (C:L), with no integrity or availability consequences, and the CVSS score of 4.3 (Medium) aligns with EPSS exploitation probability of 0.36% (29th percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a user to navigate to a crafted HTML page using Google Chrome prior to version 152.0.7977.65 - user interaction (UI:R) is a hard prerequisite confirmed by the CVSS vector, meaning passive drive-by exploitation without navigation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 Medium rating reflects a real but bounded risk: AV:N/AC:L/PR:N/UI:R captures a remotely triggerable flaw requiring no attacker privilege and only low complexity, but mandating user interaction. … 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 released in the stable channel update documented at chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
