Description

What? Once in a while, modelines appear in articles about security issues. Vim has a plugin called securemodelines to avoid these issues.

Why? The plugin should only use some options in modelines, those that do not bring any risk to our systems. It uses a variable called "secure_modelines_allowed_items".

Potential existing implementations: There is at least one vim version of secure modelines tlvince/securemodelines

Potential pitfalls: I never have developed any vim plugin, now with many Lua plugins coming out I intend to study the help the community

Contributor guide
