Description Andrej Nemec 2018-12-18 13:09:07 UTC

The debug_mode function in web/web.py in OnionShare through 1.3.1, when --debug is enabled, uses the /tmp/onionshare_server.log pathname for logging, which might allow local users to overwrite files or obtain sensitive information by using this pathname.
