AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L
UI spoofing of Autofill security indicators may expose saved credential data (C:L); no availability impact is expected from a rendering-layer flaw, making A:N more accurate than the vendor-assigned A:L.

Incorrect security UI in Autofill in Google Chrome on Windows prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI spoofing in Google Chrome's Autofill component on Windows (all versions prior to 150.0.7871.47) allows a remote unauthenticated attacker to mislead users into interacting with forged security UI elements by convincing them to perform specific on-page gestures against a crafted HTML page. Rooted in CWE-451 (UI Misrepresentation of Critical Information), the flaw enables an adversary to obscure or fabricate Autofill security indicators, potentially tricking users into submitting saved credentials or personal data to attacker-controlled destinations. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target is running Google Chrome on Windows with a version below 150.0.7871.47, and that Autofill is enabled (the default configuration for Chrome). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 4.2 (Medium) accurately reflects a constrained real-world risk profile: AC:H indicates high exploitation complexity driven by the requirement for orchestrated user UI gestures, and UI:R confirms passive exploitation is not possible. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a phishing email containing a link to a crafted HTML page designed to trigger Chrome's Autofill overlay in a misleading context - for example, a fake login form that mimics a trusted site. When the victim, running Chrome on Windows prior to 150.0.7871.47, clicks into the form field as prompted, the incorrect Autofill security UI renders, presenting a spoofed prompt that appears to be a legitimate browser-managed credential dialog. … |
| Remediation | Update Google Chrome on Windows to version 150.0.7871.47 or later, available via the stable channel and documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
