Description Adam Mariš 2017-08-16 09:20:04 UTC 
A flaw in minion id validation was found which could allow certain minions to authenticate to a master despite not having the correct credentials. To exploit the vulnerability, an attacker must create a salt-minion with an ID containing characters that will cause a directory traversal.
