Description Mauro Matteo Cascella 2023-08-23 14:20:25 UTC

When installing a maliciously created Ansible role using `ansible-galaxy role install`, arbitrary files the user has access to can be overwritten. The malicious role must contain a symlink with an absolute path to the target file, followed by a file of the same name (as the symlink) with the contents to write to the target.

Comment 4 bugzilla_throwaway 2023-09-22 09:11:24 UTC

Could you please provide the version number where this is fixed in ansible or a link to a fixing commit? Or is this still unfixed upstream?

Thanks a lot!

This was reported internally, I'm not sure there are any upstream references. Tagging vinair to elaborate further.
