| Name | CVE-2023-30801 |
| Description | All versions of the qBittorrent client through 4.5.5 use default credentials when the web user interface is enabled. The administrator is not forced to change the default credentials. As of 4.5.5, this issue has not been fixed. A remote attacker can use the default credentials to authenticate and execute arbitrary operating system commands using the "external program" feature in the web user interface. This was reportedly exploited in the wild in March 2023. |

README.Debian documents that quite clearly for the headless -nox version
When merged, the patches could still be backported as hardening, but
there's no need to treat this as a vulnerability by itself
