CVE-2026-46595
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.
Ver en NVDAnálisis
A critical vulnerability in the Go crypto/ssh package allows attackers to bypass source-address validation in SSH server configurations. This occurs when server implementations use specific callbacks other than public keys, potentially granting unauthorized network access. Developers maintaining Go-based SSH servers should update their dependencies immediately.
