EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for actual. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update actual to 26.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7rvm-xjpp-63r9 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-7rvm-xjpp-63r9 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-7rvm-xjpp-63r9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-7rvm-xjpp-63r9 in your dependencies?
O3 detects GHSA-7rvm-xjpp-63r9 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
