CVE-2024-20767 Adobe ColdFusion: login or permission bypass
In plain words: A door that should be locked is not: part of the system can be reached without a valid login or permission. The attacker gets in as a user or administrator without knowing a password.

- Put admin and file-transfer apps behind a VPN or single sign-on instead of the open internet.
