There are some submissions that we cannot accept for rewards. These are typically issues that we are already aware of, issues where business value outweighs the low-level risk, or low-risk issues unlikely to result in a code change. The following vulnerability classes are ineligible for rewards:
Denial of Service
DMARC / SPF
Malicious File Upload
Social engineering
Email Spamming / Spoofing
Content Spoofing
Clickjacking and issues only exploitable through clickjacking that has minimal impact
CSRF on forms available to anonymous users (e.g. the contact form)
CSRF with negligible security impact (e.g. adding to favourites)
Software version number disclosure
Username or Site Name enumeration
Unvalidated Open Redirects or Tab Nabbing
HTML injection
Username or email address enumeration
Phishing attack using RTLO, Unicode/Punycode
Any security weakness or missing best practice without a demonstrable security impact
Descriptive error messages
Information disclosure with minimal security impact (e.g. stack traces, path disclosure, directory listings, logs, robots.txt, etc.)
Lack of Secure and HTTPOnly cookie flags
Weak or missing captcha / captcha bypass
SSL Attacks such as BEAST, BREACH, Renegotiation attack
SSL Forward secrecy not enabled
SSL Insecure cipher suites
Missing HTTP security headers (including Anti-MIME-Sniffing header X-Content-Type-Options) that do not lead to direct exploitation
XSS only possible by an administrator (e.g. administrators can modify HTML templates)
Self-XSS that has no security impact (e.g. injecting HTML into your own RTE editor)
Reports of third-party libraries without an actual proof-of-concept
