SCA: security update for sopel-plugins.channelmgnt (GHSA-23c7-6444-399m)

high Tenable Self-Hosted Container Security Plugin ID 408626

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - sopel-channelmgnt is a channelmgnt plugin for sopel. In versions prior to 2.0.1, 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. This
 is fixed in version 2.0.1. As a workaround, do not use this plugin on networks where TARGMAX > 1.
 (CVE-2021-21431)
