Descriptions

A missing sanitization of search results for an autocomplete field in NextCloud Server <13.0.5 could lead to a stored XSS requiring user-interaction. The missing sanitization only affected user names, hence malicious search results could only be crafted by authenticated users.

La falta de saneamiento de los resultados de búsqueda para un campo de autocompletado en NextCloud Server en versiones anteriores a la 13.0.5 podría provocar un Cross-Site Scripting (XSS) persistente que requiera la interacción del usuario. La falta de saneamiento solo afectaba a los nombres de usuario, por lo que los resultados de búsqueda maliciosos solo pueden ser manipulados por los usuarios autenticados.
