Definition and Examples
Severity Rating | Definition and Examples |
---|---|
Critical |
Critical vulnerabilities are urgent security issues that present an ongoing or immediate danger to the users of our services and our infrastructure
|
High |
Typically, high severity issues are exploitable web vulnerabilities that can lead to the targeted compromise of a small number of users.
|
Moderate |
Vulnerabilities which can provide an attacker additional information or positioning that could be used in combination with other vulnerabilities. In addition to issues resulting from the lack of standard defense in depth techniques and security controls.
|
Low |
Minor security vulnerabilities which could lead to leaks or spoofs of non-sensitive information. Missing best practice security controls
|
- For *.mozilla.org, *.mozilla.com, *.mozilla.net, and *.firefox.com in addition to the list of critical and core sites.
Exclusions
Although we still appreciate being notified about them, the following issues fall outside the scope of our bug bounty program:
- Self-XSS
- Executing scripts on sandboxed domains (such as bmoattachments or mozillademos)
- CSRF for non-significant actions (logout, etc.)
- Clickjacking attacks without a documented series of clicks that produce a vulnerability
- Spam (including issues related to SPF/DKIM/DMARC)
- Denial-of-service attacks or issues related to rate limiting
- Attacks that require social engineering (phishing)
- Content injection, such as reflected text or HTML tags
- Missing HTTP headers, except as where their absence fails to mitigate an existing attack
- Authentication bypasses that require access to software/hardware tokens
- Vulnerabilities that only affect users with specific browsers (must work either in Firefox or Chrome)
- Vulnerabilities that require access to passwords, tokens, or the local system (e.g. session fixation)
- Assumed vulnerabilities based upon version numbers only
- Source code disclosures, as most of our code is open source
- Vulnerabilities discovered shortly after their public release
- Outdated TLS configurations which remain to support downloads from Windows XP systems
- Blind SSRF reports on services that are designed to load resources from the internet
- Pocket MacOS application
- Pocket iOS application until further notice
