CVE-2026-46595: golang.org/x/crypto/ssh: Invoking VerifiedPublicKeyCallback permissions skip enforcement
(updated )
Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.
