In scope

We've done our best to clean most of our known issues, and now would like to request your help to spot the ones we missed!

We are specifically looking for:

  • Accessing any user, customer, or partner sensitive information
  • PHI (Protected Health Information) and PII (Personally Identifiable Information)
  • Remote Code Execution vulnerabilities are also on our target

Extra information:

  • For FHIR and Smart Auth flows, please check the related repositories
  • Some endpoints can host OpenApi and GraphQL documentation
  • We have stage endpoints without real data corresponding to prod environment. 20 reqs/sec are accepted on stage environments. Reconnaissance techniques can be applied for discovering. Found vulnerabilities for listed assets will be accepted.

SLA internally:

We will validate all submissions within the below timelines, once your submission has been verified by Intigriti. Submissions validated outside of this may be awarded a €25 bonus. This remains at the discretion of Ada Health to award.

Vulnerability Severity Time to validate
Exceptional 2 Working days
Critical 3 Working days
High 7 Working days
Medium 15 Working days
Low 30 Working days

Working hours = Mon - Fri 9 AM - 5 PM CET

Check our fix
We offer up to €50 bonus to verify a resolved High, Critical, or Exceptional issue. This remains at the discretion of Ada Health to award.

Out of scope

Out-of-Scope Domains

You will discover the following domains when using the mobile application. Currently, these domains are not in the scope, such as;


Known issues

  • OAuth configuration issues.


  • Wordpress usernames disclosure
  • Pre-Auth Account takeover/OAuth squatting
  • Self-XSS that cannot be used to exploit other users
  • Verbose messages/files/directory listings without disclosing any sensitive information
  • CORS misconfiguration on non-sensitive endpoints
  • Missing cookie flags
  • Missing security headers
  • Cross-site Request Forgery with no or low impact
  • Presence of autocomplete attribute on web forms
  • Reverse tabnabbing
  • Bypassing rate-limits or the non-existence of rate-limits.
  • Best practices violations (password complexity, expiration, re-use, etc.)
  • Clickjacking without proven impact/unrealistic user interaction
  • CSV Injection
  • Sessions not being invalidated (logout, enabling 2FA, etc.)
  • Tokens leaked to third parties
  • Anything related to email spoofing, SPF, DMARC or DKIM
  • Content injection without being able to modify the HTML
  • Username/email enumeration
  • Email bombing
  • HTTP Request smuggling without any proven impact
  • Homograph attacks
  • XMLRPC enabled
  • Banner grabbing/Version disclosure
  • Not stripping metadata of files
  • Same-site scripting
  • Subdomain takeover without taking over the subdomain
  • Arbitrary file upload without proof of the existence of the uploaded file
  • Blind SSRF without proven business impact (pingbacks are not sufficient)
  • Disclosed/misconfigured Google Maps API keys
  • Host header injection without proven business impact


  • In case that a reported vulnerability was already known to the company from their own tests, it will be flagged as a duplicate
  • Theoretical security issues with no realistic exploit scenario(s) or attack surfaces, or issues that would require complex end user interactions to be exploited
  • Spam, social engineering and physical intrusion
  • DoS/DDoS attacks or brute force attacks
  • Vulnerabilities that only work on software that no longer receive security updates
  • Attacks requiring physical access to a victim's computer/device, man in the middle or compromised user accounts
  • Recently discovered zero-day vulnerabilities found in in-scope assets within 14 days after the public release of a patch or mitigation may be reported, but are usually not eligible for a bounty
  • Reports that state that software is out of date/vulnerable without a proof-of-concept


  • Shared links leaked through the system clipboard
  • Any URIs leaked because a malicious app has permission to view URIs opened
  • The absence of certificate pinning
  • Sensitive data in URLs/request bodies when protected by TLS
  • Lack of obfuscation
  • Path disclosure in the binary
  • Lack of jailbreak & root detection
  • Crashes due to malformed URL Schemes
  • Lack of binary protection (anti-debugging) controls, mobile SSL pinning
  • Snapshot/Pasteboard leakage
  • Runtime hacking exploits (exploits only possible in a jailbroken environment)
  • API key leakage used for insensitive activities/actions
Severity assessment

This program follows Intigriti's contextual CVSS standard


Where can we get credentials for the mobile app?

You can self-register on the application but please don’t forget to use your address.

Are domains which interact directly with the in-scope endpoints also considered to be in-scope?

Nope, only the listed assets are in the scope currently.

All aboard!
Please log in or sign up on the platform

For obvious reasons we can only allow submissions or applications for our program with a valid Intigriti account.

It will only take 2 minutes to create a new one or even less to log in with an existing account, so don't hesitate and let's get started. We would be thrilled to have you as part of our community.
