Summary
Piranha CMS through 12.2 contains a missing authorization vulnerability in the Piranha.Manager LanguageApiController that allows any authenticated manager user to list, create, edit and delete site languages without the granular Language, LanguageAdd, LanguageEdit or LanguageDelete permissions.
