Xwiki Platform licensing issue vulnerability (CNVD-2022-13405)

Xwiki Platform is a wiki platform for creating web collaboration applications from the French company Xwiki. XWiki Platform is vulnerable to an authorization issue, which stems from the fact that even if the wiki is closed to visitors, it is possible to guess whether a user has an account on the wiki by using a forgotten password form, which could be exploited by an attacker to guess the existence of a user .
