Description

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.10 and 2.11.5, the configured SMTP server may be spoofed with any certificate (e.g. self-signed), leaving credentials and all emails sent open to MITM attacks. This vulnerability is fixed in 2.10.10 and 2.11.5.
