Introducción
Level runs quarterly penetration tests and actively monitors for vulnerabilities, but real-world use surfaces things automated testing misses. If you find a security issue, we want to hear about it.
Send reports to [email protected].
ℹ️ NOTA: If you're creating a test account specifically for vulnerability research, add "Tester" to your email address (e.g., [email protected]) so we can filter those accounts from our metrics.
Report Seguridad Vulnerability
What to Include in Your Report
A useful report gets addressed faster. Include:
A clear, step-by-step description of how to reproduce the vulnerability
The specific asset affected (see Assets in Scope below)
An attack scenario demonstrating the potential impact
Screenshots, video, or proof-of-concept code if applicable
Reports without reproduction steps and an impact scenario can't be acted on.
Assets in Scope
Web app: https://app.level.io
API: https://api.level.io
Agent API: https://agents.level.io
Level agent: Windows, macOS, and Linux
In-Scope Issues
We want reports on:
Authentication and session management — sign-in flows, session handling, OAuth, account recovery, password policies
Access control — permission bypasses, CSRF, unauthorized access between accounts
Injection vulnerabilities — SQL injection, XSS, and other input-based attacks
Cross-customer device access — any path that lets one customer access another customer's managed devices
Account-level vulnerabilities — malware upload, phishing URL embedding, RTLO/IDN homograph attacks from untrusted users on the same account
Testing must be done on your own Level accounts. If you need a sandbox environment, contact us before testing.
Out-of-Scope Issues
These won't be accepted. Don't submit reports for:
Behavior we've assessed and accepted:
Rate limiting
Best-practice concerns without evidence of an exploitable vulnerability
Sessions not invalidating when 2FA is enabled
Vulnerabilities only affecting users on outdated, unpatched browsers
Race conditions with no security impact
CSRF on actions with no security impact (login, logout, unauthenticated pages)
Theoretical risks without a demonstrated attack path
Salida from automated scanners without explanation
Infrastructure / configuration noise:
Email spoofing / SPF / DKIM / DMARC policies
Hyperlink injection in emails
Missing security headers unless tied to a specific vulnerability
SSL/TLS cipher issues without a working proof of concept
Banner grabbing and software version disclosure
Open ports without a demonstrated vulnerability
DNSSEC / DANE
HSTS or CSP headers
Disclosure of known public files (e.g.,
robots.txt)Usuarioname or email enumeration
Autocomplete attributes on web forms
Operational issues:
Denial of service against other customers' accounts
Social engineering of any kind against other customers or Level staff
Spearphishing attempts or contacting support as part of testing
Physical intrusion
Automated scanning, mail bombing, spam, brute-forcing, or automated attacks (e.g., Burp Intruder)
Leaking, manipulating, or destroying user data
Specific DoS exclusions:
DoS via malformed inputs or crafted file uploads triggering 500 errors
DoS via unlimited or very large password inputs
DoS via lack of pagination or large amounts of user-generated content slowing responses
Disqualifiers
Reports are disqualified if they:
Lack step-by-step reproduction instructions
Involve accessing other customers' accounts
Involve social engineering Level staff or customers
Use automated attack tools against Level infrastructure
Result in leaking, modifying, or destroying user data
Preguntas frecuentes
Where do I send vulnerability reports? Email [email protected] with full reproduction steps and an impact scenario.
Do you have a bug bounty program? No, we don't have a bug bounty program. Contact [email protected] with questions.
Can I test against other customers' accounts? No. Testing must be done on your own Level accounts. Accessing other customers' accounts is an immediate disqualifier and may have legal consequences. Contact us if you need a sandbox environment.
My report includes output from an automated scanner. Will that work? Only if it's accompanied by a clear explanation of the vulnerability, reproduction steps, and an attack scenario. Raw scanner output alone won't be acted on.
How quickly will you respond? Response times aren't guaranteed. Contact [email protected] directly if you have an urgent disclosure.
