CVE-2025-4412

TCC Bypass via Dylib Loading in Viscosity.app

On macOS systems, by utilizing a Launch Agent and loading the viscosity_openvpn process from the application bundle, it is possible to load a dynamic library with Viscosity's TCC (Transparency, Consent, and Control) identity. The acquired resource access is limited without entitlements such as access to the camera or microphone. Only user-granted permissions for file resources apply. Access to other resources beyond granted-permissions requires user interaction with a system prompt asking for permission.

This issue was fixed in version 1.11.5 of Viscosity.
