Description

CERT Polska has received a report about vulnerabilities in two macOS applications and participated in coordination of its disclosure.

Poedit

The vulnerability CVE-2025-4280: MacOS version of Poedit bundles a Python interpreter that inherits the Transparency, Consent, and Control (TCC) permissions granted by the user to the main application bundle. An attacker with local user access can invoke this interpreter with arbitrary commands or scripts, leveraging the application's previously granted TCC permissions to access user's files in privacy-protected folders without triggering user prompts. Accessing other resources beyond previously granted TCC permissions will prompt the user for approval in the name of Poedit, potentially disguising attacker's malicious intent.

This issue has been fixed in 3.6.3 version of Poedit.

Viscosity

The vulnerability CVE-2025-4412: 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.
