Detailsinfo

A vulnerability was found in Arduino arduino-ide up to 2.3.6 on macOS. It has been rated as critical. This issue affects some unknown functionality of the component Hardened Runtime Protection. The manipulation with an unknown input leads to a default permission vulnerability. Using CWE to declare the problem leads to CWE-276. During installation, installed file permissions are set to allow anyone to modify those files. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2025-64723 since 11/10/2025. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1222 for this issue.

Upgrading to version 2.3.7 eliminates this vulnerability. The upgrade is hosted for download at github.com. Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
