I just noticed that the configuration file of my Wikidata Lexeme Forms tool on Toolforge was world-readable.
lucaswerkmeister@tools-sgebastion-07:~$ ls -l ~tools.lexeme-forms/www/python/src/config.yaml -rw-r--r-- 1 tools.lexeme-forms tools.lexeme-forms 161 Apr 25 2020 /data/project/lexeme-forms/www/python/src/config.yaml
I’ve fixed this now, but I should replace the OAuth consumer as well, since any Toolforge user could’ve stolen the credentials in the past year or so.
