AI-suggested
Upgrade to Actual version 26.5.0 or later, where this vulnerability is patched. No other official remediation or temporary fix is documented. Until upgrading, restrict the ability of untrusted users or processes to place files or control command-line arguments used to launch Actual.app on macOS.
Description
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.
