CVE-2025-4081

Use of entitlement com.apple.security.cs.disable-library-validation and lack of launch and library load constraints allows to substitute a legitimate dylib with malicious one. A local attacker with unprivileged access can execute the application with altered dynamic library successfully bypassing Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission.

This issue affects DaVinci Resolve on macOS in all versions. Last tested version: 19.1.3

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Potential Mitigations

• 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.
