CVE-2025-64723: Arduino IDE for macOS has TCC Bypass via Dynamic Library Injection

• Severity: medium (CVSS 4.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-12-18 · updated 2026-06-17
• Weakness: CWE-276

Description

Arduino IDE is an integrated development environment. Prior to version 2.3.7, Arduino IDE for macOS was configured with overly permissive security entitlements that could bypass macOS Hardened Runtime protections. This configuration allows attackers to inject malicious dynamic libraries into the application process, gaining access to all TCC (Transparency, Consent, and Control) permissions granted to the application. The fix is included starting from the `2.3.7 ` release.

Affected products

• arduino-ide: before 2.3.7 — fixed in 2.3.7

How to fix

Upgrade to a fixed version: arduino-ide 2.3.7. Check the vendor advisory for mitigations.
