Current behavior
The vulnerability CVE-2023-48795 requires ssh2 1.15 and above to fix: mscdex/ssh2#1354
The tunnel-ssh 4.x series, which is a dependency of db-migrate, only supports ssh2 up to 1.4.0: #755. This CVE can be resolved for db-migrate if the tunnel-ssh dependency is upgraded to 5.x (or if tunnel-ssh updates its 4.x dependencies, but it's been a year since 5.x was released).
Expected behavior
The security vulnerability should be addressed.
