Secure Shell vulnerabilitiesRanked by how likely they are to be used.
Secure Shell is made by SSH. We track 3 published vulnerabilities listed under that exact name, across 5 versions. None of them is on the list of flaws known to be exploited today. SSH lists newer releases under their own names, such as Secure Shell for Servers, so check those pages too.
We keep watching the known-exploited list.
Is Secure Shell listed under other names? Yes.
SSH also lists Secure Shell under more specific names, such as Secure Shell for Servers. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.

Which Secure Shell flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.

1 new flaw affects software Acme tracks
SSH 1.2.25, 1.2.23, and other versions, when used in in CBC (Cipher Block Chaining) or CFB (Cipher Feedback 64 bits) modes, allows remote attackers to insert arbitrary data into an existing stream between an SSH client and server by using a known plaintext attack and computing a valid CRC-32 checksum for the packet, aka the "SSH insertion attack."
