CVE-2026-25933
6.8 · MEDIUMOverview
CVE-2026-25933 is a medium-severity vulnerability affecting arduino app_lab. It was published on February 12, 2026 and has a CVSS 3.1 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
Arduino App Lab is a cross-platform IDE for developing Arduino Apps. Prior to 0.4.0, a vulnerability was identified in the Terminal component of the arduino-app-lab application. The issue stems from insufficient sanitization and validation of input data received from connected hardware devices, specifically in the _info.Serial and _info.Address metadata fields. The problem occurs during device information handling. When a board is connected, the application collects identifying attributes to establish a terminal session. Because strict validation is not enforced for the Serial and Address parameters, an attacker with control over the connected hardware can supply specially crafted strings containing shell metacharacters. The exploitation requires direct physical access to a previously tampered board. When the host system processes these fields, any injected payload is executed with the privileges of the user running arduino-app-lab. This vulnerability is fixed in 0.4.0.
Remediation
Check the references section for vendor advisories and patches from arduino. Update app_lab to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
