CVE-2019-9140
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWhen processing Deeplink scheme, Happypoint mobile app 6.3.19 and earlier versions doesn't check Deeplink URL correctly. This could lead to javascript code execution, url redirection, sensitive information disclosure. An attacker can exploit this issue by enticing an unsuspecting user to open a specific malicious URL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Happypoint mobile app versions 6.3.19 and earlier fail to properly validate Deeplink URLs during processing. This improper URL checking allows attackers to inject malicious JavaScript code through crafted deeplink URLs, potentially leading to arbitrary script execution in the app's WebView component, unauthorized URL redirection to attacker-controlled sites, and exposure of sensitive application data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Happypoint app versionOn Android: Go to Settings > Apps > Happypoint > Version info. On iOS: Go to Settings > General > iPhone Storage > Happypoint to view version number.Affected if Version is 6.3.19 or earlier (e.g., 6.3.19, 6.3.18, 6.3.17, etc.)
-
Verify deeplink handler configurationInspect the app's AndroidManifest.xml (Android) or Info.plist (iOS) for deeplink intent filters or URL schemes registered (such as happypoint://, hp://, or similar custom schemes).Affected if Deeplink URL schemes are registered and the app processes external URLs without proper validation
-
Check WebView configuration for deeplink handlingReview app source code or network traffic for deeplink URLs being loaded into WebView components via loadUrl() or evaluateJavascript() methods.Affected if Deeplink URLs are directly passed to WebView without sanitization
-
Monitor for suspicious URL patterns in app trafficUse a network proxy (e.g., Burp Suite, Charles) to capture app traffic and look for deeplink URLs containing javascript:, data:, or unusual query parameters that may indicate injection attempts.Affected if Deeplink URLs contain unvalidated dynamic content or are being redirected to external untrusted domains
You are affected if the Happypoint mobile app version is 6.3.19 or earlier and the app has deeplink functionality enabled that processes URLs into WebView without validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Happypoint to a version newer than 6.3.19, and implement proper Deeplink URL validation and sanitization before processing to prevent injection attacks.
