Attack delivery is via a crafted HTML page (network vector); user must interact (UI:R); confidentiality-only impact from cross-origin data leak; 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.

Insufficient validation of untrusted input in PDF in Google Chrome on Android prior to 151.0.7922.72 allowed a local attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's PDF component on Android (prior to 151.0.7922.72) exposes sensitive data from one web origin to an attacker-controlled page due to insufficient input validation in PDF processing. A local attacker who can direct a victim to a crafted HTML page triggers the flaw, allowing confidentiality impact with no integrity or availability consequence. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on an Android device with a version prior to 151.0.7922.72, and must interact with a crafted HTML page that triggers the vulnerable PDF processing code path - user interaction is required and confirmed by UI:R in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) reflects high confidentiality impact with no complexity barrier once user interaction occurs. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing malicious PDF content or PDF-triggering logic designed to exploit the validation gap in Chrome's Android PDF component. When a victim on an Android device visits this page using an unpatched Chrome browser - whether via a phishing link, malicious ad, or QR code - Chrome's PDF processing is triggered without properly validating cross-origin boundaries, causing sensitive data from other origins (such as session tokens, cookies, or local storage content) to be read by the attacker's page. … |
| Remediation | Vendor-released patch: Chrome 151.0.7922.72 for Android, detailed in the stable channel update advisory at chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
