 ## Reporting a Vulnerability
 
 **Please do not file a public ticket** mentioning the vulnerability.
 
-To find out how to disclose a vulnerability in Ethereum visit [https://bounty.ethereum.org](https://bounty.ethereum.org) or email [email protected].
+To find out how to disclose a vulnerability in Ethereum visit [https://bounty.ethereum.org](https://bounty.ethereum.org) or email [email protected]. Please read the [disclosure page](https://github.com/ethereum/go-ethereum/security/advisories?state=published) for more information about publically disclosed security vulnerabilities.
