Description Andrej Nemec 2016-09-19 14:54:36 UTC 
Due to a recent migration of the Gallery app to the new sharing endpoint a parameter changed from an integer to a string value. This value wasn't sanitized before and was thus now vulnerable to a Cross-Site-Scripting attack.

To exploit this vulnerability an authenticated attacker has to share a folder with someone else, get them to open the shared folder in the Gallery app and open the sharing window there.

Since ownCloud employs a strict Content-Security-Policy this vulnerability is only exploitable in browsers not supporting Content-Security-Policy.
