## What is CVE-2025-64724?

CVE-2025-64724 is a medium-severity vulnerability in arduino-ide, published on 18 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Arduino IDE is an integrated development environment. Prior to version 2.3.7, Arduino IDE for macOS is installed with world-writable file permissions on sensitive application components, allowing any local user to replace legitimate files with malicious code. When another user launches the application, the malicious code executes with that user's privileges, enabling privilege escalation and unauthorized access to sensitive data. The fix is included starting from the `2.3.7` release.

Weakness: CWE-276 (Incorrect Default Permissions)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-64724 and fix it if it is affected.

What it is: CVE-2025-64724 is a medium-severity vulnerability in arduino-ide, published on 18 Dec 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-64724 in the wild and no public exploit code.

Affected product: arduino-ide. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
