Insufficient policy enforcement in Autofill in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's Autofill subsystem prior to version 151.0.7922.72 enables a remote attacker to read data across origin boundaries by luring a victim to a crafted HTML page. The flaw is rooted in insufficient policy enforcement (CWE-346: Origin Validation Error) within Chrome's Autofill feature, which fails to correctly gate form data access by origin. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is a hard prerequisite: a victim must navigate to and load the attacker-controlled HTML page in an unpatched Chrome browser, as confirmed by the CVSS UI:R metric and SSVC's 'not automatable' rating. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (Medium) is consistent with the actual signal set: the attack vector is network (AV:N) and requires no privileges (PR:N), but user interaction is mandatory (UI:R) and the impact is limited to partial confidentiality disclosure (C:L) with no integrity or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing form elements engineered to trigger Chrome's Autofill subsystem in a manner that bypasses its origin validation logic. When a victim with Autofill enabled navigates to the page, Chrome incorrectly surfaces cross-origin Autofill data - such as saved address or form values associated with a different origin - which the attacker's page script can then read and exfiltrate. … |
| Remediation | The primary fix is upgrading Google Chrome to version 151.0.7922.72 or later via the browser's built-in update mechanism (Settings > Help > About Google Chrome) or enterprise deployment tooling; details are available at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
