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.

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?
If you ran your browser as root and configured your browser to load local resources on non-local domains maybe. I think you can do that in chrome://flags but you have to explicitly list the domains allowed to do it.
I’m hoping this is just a bad joke.

you don’t need to be root to read
/etc/passwdThat’s because passwd doesn’t store the password hashes. Just user names.
Are you sure? What do you get when you run
$ cat /etc/passwdin terminal? Just paste the results here 😇Edit: to anyone reading this on the future, don’t actually do this, it was a joke
yup pretty sure
$ cat /etc/passwd fox:hunter2:1000:1000::/home/fox:/usr/bin/zsh😉
Weird, all I see is *******
Since you told me not to. There isn’t a risk on most linux systems; passwords were moved to /etc/shadow a long time ago. It only leaks the names of your users and largely useless info for most attackers:
