Overview
github.com/mattermost/mattermost-server/v6 is an open source, private cloud, Slack-alternative.
Affected versions of this package are vulnerable to URL Redirection to Untrusted Site ('Open Redirect') due to the improper validation of a redirect URL parameter, an attacker can manipulate the redirection process to lead users to unintended and potentially malicious websites by providing an invalid custom URL scheme in the /oauth/{service}/mobile_login?redirect_to= endpoint. This is only exploitable if the user clicks on the "Back to Mattermost" button after the invalid custom URL scheme has been provided.
