Are there any open source data for English words by CEFR level?
I found https://www.oxfordlearnersdictionaries.com/wordlists/oxford3000-5000 , which categorizes English words based on CEFR level, but it has license.

Cambridge University Press is making the A1-C2 English Vocabulary Profile available free of charge to teachers and educationalists around the world. Go to EVP Online to access the resource.
Maybe this word lists link is what you are looking for. It is a course with lists of words as pdfs categorized by CEFR levels.
Alternatively, you can use the EFLLex: A CEFR-graded lexical resource for English as a foreign language, which is open sourced but the you still must cite the original work/ authors.
