Official description
ColdFusion versions 2025.1, 2023.13, 2021.19 and earlier are affected by an Improper Access Control vulnerability that could result in arbitrary file system read. A high-privileged attacker could leverage this vulnerability to access or modify sensitive data without proper authorization. Exploitation of this issue does not require user interaction, and scope is changed.

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
