Description Guilherme de Almeida Suckevicz 2020-06-01 19:21:31 UTC 
In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua).

Reference and upstream commit:
https://github.com/vim/vim/releases/tag/v8.1.0881
https://github.com/vim/vim/commit/8c62a08faf89663e5633dc5036cd8695c80f1075
Comment 1 Huzaifa S. Sidhpurwala 2020-06-02 03:44:49 UTC 
Created vim tracking bugs for this issue:

Affects: fedora-all [bug 1842752]
Comment 4 Huzaifa S. Sidhpurwala 2020-06-02 03:53:05 UTC 
Statement:

Upstream suggests that users may still find loopholes to execute a shell commands, it has only been made difficult. So administrators should not assume that vim restricted mode will completely disable execution of OS commands.
