## Summary

The mycli command-line MySQL/MariaDB client, a database tool built by dbcli, is affected through a flaw in its special-command safety check (the "Whitelist" component used for the source command). An attacker with local access could exploit this to inject operating system commands, potentially gaining control of the affected user's system.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- dbcli mycli: 2.29.0, 2.29.1, 2.29.2, 2.29.3, 2.29.4, 2.30.0, 2.30.1

## Description

A weakness has been identified in dbcli mycli up to 2.29.4/2.30.1. The impacted element is the function source_special_command_is_safe of the file mycli/packages/special/source.py of the component Whitelist. Executing a manipulation can lead to os command injection. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
