Remote code execution in the WarnSystem module of Laggrons-Dumb-Cogs

WarnSystem is a cog (plugin) for the Red discord bot. A vulnerability has been found in the code that allows any user to access sensible informations by setting up a specific template which is not properly sanitized. The problem has been patched in version 1.3.18. Users should update and type `!warnsysteminfo` to check that their version is 1.3.18 or above. As a workaround users may unload the WarnSystem cog or disable the `!warnset description` command globally.

tj-actions/changed-files command injection in output filenames

tj-actions/changed-files is a Github action to retrieve all files and directories. Prior to 41.0.0, the `tj-actions/changed-files` workflow allows for command injection in changed filenames, allowing an attacker to execute arbitrary code and potentially leak secrets. This issue may lead to arbitrary command execution in the GitHub Runner. This vulnerability has been addressed in version 41.0.0. Users are advised to upgrade.
