Description Sam Fowler 2018-08-22 03:59:14 UTC
Nextcloud Server before version 13.0.5 is vulnerable to missing sanitization of search results for an autocomplete field allowing for stored XSS requiring user-interaction. The missing sanitization only affected user names, hence malicious search results could only be crafted by authenticated users.
