Description Oleg Sushchenko 2026-10-27 20:48:26 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
