Description

actual Allows Electron to Run As Node

Summary

A electron run as node vulnerability was identified in actual (macOS application, version 25.x (Electron 39.2.7)).

Vulnerability Type: Electron Run As Node

Description

ELECTRON_RUN_AS_NODE fuse enabled (Electron 39.2.7) — app can be converted to Node.js REPL for arbitrary code execution

Impact

An attacker who can place a file on disk or control command-line arguments can invoke the signed Actual.app binary with ELECTRON_RUN_AS_NODE=1 to execute arbitrary Node.js code inheriting the apps entitlements and code signature. This bypasses macOS Gatekeeper review of the payload: the Node.js script runs as Actual, under Actuals bundle ID and signed identity, and has access to any entitlements the app carries (network, file access, keychain, automation). Combined with any downloader (browser, mail attachment, Slack link) this becomes a signed-binary-abuse primitive on every Mac with Actual installed.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. Rated impact: confidentiality low, integrity none, availability none.

Weakness class

CVE-2026-42890 is classified as CWE-250: Execution with Unnecessary Privileges. The software runs with more privilege than the task needs, so any flaw in it inherits that privilege.
