CVE-2021-36370:

An issue was discovered in Midnight Commander through 4.8.26. When establishing an SFTP connection, the fingerprint of the server is neither checked nor displayed. As a result, a user connects to the server without the ability to verify its authenticity.


Fixed in 4.8.27 according to https://midnight-commander.org/wiki/NEWS-4.8.27.
Please remember to file security bugs when there are security issues in
changelogs!

Please stabilize 4.8.27.
