Introduction

We are happy to announce our program! We've done our best to clean up our known issues and now would like to request your help to spot the ones we missed!

Our worst-case scenarios are:

• Data breach, we care about our Members' privacy on our platform.
• Loss of Members' trust.
• Operational Disruption, no one likes when things go haywire.

We're also looking for:

• Any logical errors that can cause reputational damage for sellers or buyers.
• Any logical errors that can cause fraud activities for Vinted users or Vinted itself

Depending on the report, these can be treated at a higher severity or payout by Vinted

Feedback

vinted.ca is not in scope until further notice
people.vinted.* is not in scope untill further notice

/API/V2/ - City name leakage

AWS Specific

• Publically readable S3 buckets. We have a selection of our S3 buckets available to the Internet as caches for our website and other public resources - UNLESS it is clear that the information should not be public, i.e. personal data, company confidential files and such. Please log a ticket if you're not sure with examples of the folder structure (do not download the data)

Application

• API key disclosure without proven business impact
• Wordpress usernames disclosure
• Pre-Auth Account takeover/OAuth squatting
• Self-XSS that can't 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
• Results of automated scanners
• 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 aren't sufficient)
• Disclosed/misconfigured Google Maps API keys
• Host header injection without proven business impact

General

• 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

Mobile

• 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
