What is CVE-2025-67750?
CVE-2025-67750 is a high-severity code injection vulnerability in lightning-flow-scanner, published on 12 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Lightning Flow Scanner provides a A CLI plugin, VS Code Extension and GitHub Action for analysis and optimization of Salesforce Flows. Versions 6.10.5 and below allow a maliciously crafted flow metadata file to cause arbitrary JavaScript execution during scanning. The APIVersion rule uses new Function() to evaluate expression strings, enabling an attacker to supply a malicious expression within rule configuration or crafted flow metadata. This could compromise developer machines, CI runners, or editor environments. This issue is fixed in version 6.10.6.
Weakness: CWE-94
