Official description
GlobaLeaks is free and open-source whistleblowing software. Prior to version 5.0.89, the /api/support endpoint of GlobaLeaks performs minimal validation on user-submitted support requests. As a result, arbitrary URLs can be included in support emails sent to administrators. Version 5.0.89 patches the issue.
