  • Jsbridge/javascritptinterface that can be called to harm users.
  • Other vulnerabilities that may result in potential loss.

The following security issues are not within scope.

1. Web Module

  • Theoretical loopholes that are not actually proven.
  • Email verification code flaws, expired password reset links, and issues with password complexity policies.
  • Records with invalid or missing sender information.
  • Clickjacking and UI redirection with only minor security impact.
  • Vulnerabilities in third-party applications.
  • Zero-day exploits that are less than 30 days old.
  • Social engineering, phishing, and other forms of deception.
  • Denial of service (DOS) attacks.
  • Email/phone number information enumeration (e.g. resetting passwords to verify emails or phone numbers).
  • Data leaks with minor security impact (e.g. stack tracing, path exposure, directory listing, and log information).
  • Known issues, duplicate submissions, or security issues that have already been disclosed.
  • Physical attacks.
  • XSS for PCs.
  • Vulnerabilities that can only be exploited on older versions of browsers or platforms.
  • Vulnerabilities in auto-filling web forms.
  • Using known codebase vulnerabilities without actual proof.
  • Lack of security flags in cookies.
  • Issues related to insecure SSL/TLS socket or protocol versions.
  • Content-based deception.
  • Issues related to cache management.
  • Internal IP or domain name leakages.

2. Mobile Module

  • Vulnerabilities that require Root/Jailbreak permissions.
  • Physical vulnerabilities that require manipulation of the user's device.
  • Vulnerabilities that require a lot of user interaction.
  • Issues that only expose non-sensitive device information.
  • Only static analysis is performed on binary files with missing POC business logic.
  • Lack of fuzzing, binary protection, or root (jailbreak) detection.
  • Bypassing of device certificate detection.
  • Missing Exp such as PIE, ARC, or stack exploits.
  • Leakage of sensitive information in TLS-protected URLs or Requests.
  • Binary path leaks.
  • Hardcoded OAuth and APP keys present in APK and IPA.
  • Scan reports for automated tools.
  • Information leakage caused by sensitive information being stored in clear text in the user device.
  • Crashes caused by sending malformed URL Schemes or components to receivers such as external Activity/Service/Broadcast (the leakage of sensitive data obtained by exploiting these schemes is within the scope of acceptable vulnerabilities).
  • Shared link leaks via clipboard.
  • API key leaks with no security implications (such as Google Map API keys).
  • Other content outlined in the out of scope Web Module vulnerabilities.

  • Serious SQL injections.
  • High-risk data leaks.

P3 200 - 400 USD:
