I am trying to understand the level of access which the Groovy Script Runner has to the DB. Given that it can rename users, I assume it has update access. Assuming that the DB user which JIRA is using to access the DB has permissions on other DB's, could the plugin actually open new connections to them? Assuming the user making the connection has the right permissions, can the plugin modify other user's permissions? Can it execute arbitrary SQL?
Cheers,
Boris
