Advisories for Pypi/Sopel-Plugins.channelmgnt package

On some IRC servers, restrictions around the removal of the bot using the kick/kickban command could be bypassed when kicking multiple users at once. We also believe it may have been possible to remove users from other channels but due to the wonder that is IRC and following RfCs, We have no POC for that. Freenode is not affected.

In the Channelmgnt plug-in for Sopel before version 1.0.3, malicious users are able to op/voice and take over a channel. This is an ACL bypass vulnerability. This plugin is bundled with MirahezeBot-Plugins with versions from 9.0.0 and less than 9.0.2 affected. Version 9.0.2 includes 1.0.3 of channelmgnt, and thus is safe from this vulnerability.
