Incorrect authorization 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
Web origin policy bypass in Google Chrome's network layer prior to version 152.0.7977.65 allows a remote attacker to circumvent the browser's same-origin enforcement by luring a user to a crafted HTML page. The flaw stems from incorrect authorization logic (CWE-863) in Chrome's networking stack, resulting in limited confidentiality exposure (C:L) with no integrity or availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim use Google Chrome prior to version 152.0.7977.65 and actively visit a crafted HTML page under attacker control - the CVSS UI:R metric confirms this user-interaction prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) reflects an accessible but impact-limited vulnerability: AV:N and AC:L mean no special network position is needed, but UI:R anchors exploitation to user interaction, and the impact is confined to C:L with no integrity or availability component. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a malicious domain and hosts a crafted HTML page that exploits the incorrect network authorization logic in Chrome's origin enforcement. The attacker distributes a link via email or social media; when a victim running an unpatched Chrome version clicks the link and the page loads, the origin policy check is bypassed, potentially allowing the attacker's page to read limited cross-origin data from another site the victim is authenticated to. |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, which resolves this flaw per the vendor's 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. |
