Network-delivered via crafted page (AV:N); mandatory specific UI gestures required (UI:R); impact limited to low cross-origin data disclosure with no integrity or availability effect.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Inappropriate implementation in Passwords in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who convinced a user to engage in specific UI gestures to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's Passwords component (versions prior to 151.0.7922.72) stems from an inappropriate implementation classified under CWE-346 (Origin Validation Error), enabling a remote attacker to exfiltrate limited cross-origin credential-related data via a crafted HTML page. Exploitation requires the target user to perform specific, undisclosed UI gestures - such as interacting with a password field or autofill prompt - on the attacker's page, limiting mass-scale automation. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three simultaneous conditions: (1) the target must be running Google Chrome prior to version 151.0.7922.72; (2) the attacker must successfully social-engineer the user into visiting a crafted HTML page; and (3) the user must perform 'specific UI gestures' on that page - the exact gestures are undisclosed but the CVSS UI:R metric confirms they are mandatory and non-trivial, ruling out passive drive-by exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 Medium score is consistent with the limited impact profile: C:L (low confidentiality), I:N, A:N, S:U. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page designed to trigger Chrome's Passwords component via user UI interactions - for example, a fake login form that prompts the user to click or interact with a field, inadvertently invoking the autofill/password-suggestion mechanism. The origin-validation flaw causes Chrome to expose cross-origin credential-related data back to the attacker's page JavaScript, which the attacker can then exfiltrate. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, as released in the stable channel update documented at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
