Timeline

2026-01-07	first spoke of it: curl: Host verification bypass during SSH transfers	Red Hat
2026-01-08	first spoke of it: When doing SSH-based transfers using either SCP or SFTP, and setting the known_hosts file, libcurl could still mistakenly accept connecting to hosts not present in the specified file if they were added as recognized in the libssh global known_hosts file.	NVD

What it is to other things

affects	haxx/curl NVD
made_by	haxx NVD

In words only, so not counted until a person confirms one:

made_by	`curl` NVD says “curl”
affects	`curl/curl` NVD says “curl · curl”

Every value, with what each source said and its receipt
