Doesn't work due to clipboard entry parsing about gnome-shell-extension-clipboard-indicator HOT 10 CLOSED

Not sure why would the extension try to open a random file? Did you edit the registry.txt file?

Did you edit the registry.txt file?

Don't know what that is.

Extension wasn't working as expected (refer #439 (comment)) for more than a week. I thought it was due to recent GNOME Shell 46 upgrade stuff. As the issue wasn't going away, I decided to look into journalctl logs to fix the issue, as I wanted to get the extension working.

Hmm interesting. If that every happens to you again, I would appreciate if you could make a copy of ~/.cache/[email protected]/registry.txt and send it to me privately (remember to remove any sensitive information from it before sending it to me).

Do I understand correctly that the extension is currently working for you?

I'm having the same issue, every time I copy a system's directory path, the app tries to open it for some reason, and fails with the message stated in the issue. The fix, is to mv the path so that it doesn't exist anymore and re-enable the extension, then delete the entry containing the path and move the path back again in the file system.

I can reproduce it at any time I want, so let me post the registry.txt file.

$ cat ~/.cache/[email protected]/registry.txt
[{"favorite":false,"mimetype":"UTF8_STRING","contents":"/home/edu4rdshl/.local/share/applications"},{"favorite":false,"mimetype":"text/plain;charset=utf-8","contents":".local/share/applications/"},{"favorite":false,"mimetype":"text/plain;charset=utf-8","contents":"/var/lib/pacman/local"}]

After checking, the issue is when the mimetype is set to UTF8_STRING, I can reproduce it for each line if I change the mimetype to that one. And, changing it to text/plain;charset=utf-8 makes the issue disappear.

Thanks! This sounds like a bug. Will try to reproduce.

@Edu4rdSHL from what app are you copying the path?

from gnome-shell-extension-clipboard-indicator.

Out of curiosity, why is even the app trying to execute something? That looks terrible to me. So, if I copy rm -rf $HOME and it gets set to UTF8_STRING, it will possibly run that?

Edit: I confirm this behavior. We have a RCE vulnerability right here. I will open a new issue to track it.

from gnome-shell-extension-clipboard-indicator.

@Edu4rdSHL I honestly have no idea. I don't understand how that could happen.

from gnome-shell-extension-clipboard-indicator.

Ran into this issue again.

Steps to reproduce:

1. Clear all entries
2. Copy /tmp/ to clipboard.
3. Disable and enable extension
4. Below error should happen.
