Summary
Actual is an open-source personal finance application. In the macOS desktop application version 25.x (built on Electron 39.2.7), the ELECTRON_RUN_AS_NODE fuse is not disabled, allowing an attacker to invoke the signed Actual.app binary with the ELECTRON_RUN_AS_NODE=1 environment variable set, turning the application into a Node.js REPL capable of executing arbitrary code.
Risk Assessment
Exploitation of this vulnerability could lead to the execution of malicious code that inherits the application's entitlements and code signature, bypassing macOS Gatekeeper review. This poses serious security risks to user data.
Recommendation
It is recommended to update the Actual application to version 26.5.0, which patches this vulnerability. Additionally, monitor and restrict the ability to place files on disk by unauthorized entities.
Original NVD description (English source)
Actual is an open-source personal finance application. In the macOS desktop application version 25.x (built on Electron 39.2.7), the ELECTRON_RUN_AS_NODE fuse is not disabled, allowing an attacker who can place a file on disk or control command-line arguments to invoke the signed Actual.app binary with the ELECTRON_RUN_AS_NODE=1 environment variable set. This converts the application into a Node.js REPL capable of executing arbitrary code that inherits the application's entitlements and code signature, bypassing macOS Gatekeeper review. Version 26.5.0 patches the issue.
