FKIE_CVE-2025-4412

Vulnerability from fkie_nvd - Published: 2025-05-27 10:15 - Updated: 2026-06-17 09:33
Severity
4.8 (Medium) - CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N
Summary
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.
