Found the error Not allowed to load local resource: file:///etc/passwd while looking at infosec.pub's communities page. There's a community called "ignore me" that adds a few image tags trying to steal your passwd file.
You have to be extremely poorly configured for this to work, but the red flags you see should keep you on your toes for the red flags you don't.
Holy shit this is kind of unsettling. Though I would expect ALL major browsers to reject reading any local files like this..... would this kind of thing actually succeed somewhere/somehow?
