arduino arduino-app-lab up to 0.3.x Terminal _info.Serial/_info.Address os command injection

Summaryinfo

A vulnerability was found in arduino arduino-app-lab up to 0.3.x. It has been declared as critical. Impacted is an unknown function of the component Terminal Component. The manipulation of the argument _info.Serial/_info.Address results in os command injection. This vulnerability is cataloged as CVE-2026-25933. An attack on the physical device is feasible. There is no exploit available. It is recommended to upgrade the affected component.

Detailsinfo

A vulnerability classified as critical has been found in arduino arduino-app-lab up to 0.3.x. Affected is some unknown processing of the component Terminal Component. The manipulation of the argument _info.Serial/_info.Address with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-25933 since 02/09/2026. The exploitability is told to be difficult. Local access is required to approach this attack. Additional levels of successful authentication are needed for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

Upgrading to version 0.4.0 eliminates this vulnerability. The upgrade is hosted for download at github.com.
