Nextcloud Server before 9.0.55 and 10.0.2 suffers from a Content-Spoofing vulnerability in the "files" app. The top navigation bar displayed in the files list contained partially user-controllable input leading to a potential misrepresentation of information.

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are vulnerable to a content-spoofing attack in the files app. The location bar in the files app was not verifying the passed parameters. An attacker could craft an invalid link to a fake directory structure and use this to display an attacker-controlled error message to the user.
