If you uncover a security vulnerability in Sakai software please do not voice your concerns on any public listserv, blog or other open communication channel but instead notify the Sakai Foundation immediately at security@sakaifoundation.org. Please provide a callback telephone number so that we can contact you by telephone if it is deemed necessary.

See the policy here: https://confluence.sakaiproject.org/display/SECWG/Security+Policy

If you create a login here: https://jira.sakaiproject.org/secure/Dashboard.jspa

You can report the security issue by creating an issue and setting the Security Level pulldown to "Security Issue" Thanks
