YesWiki 4.5.0 before 4.7.0 contains an SQL injection vulnerability in PageManager::save(), where the date_maj_fiche field of a Bazar entry-creation request is concatenated unescaped into an INSERT statement. Unauthenticated attackers on default installs can inject a sub-SELECT against wiki_users to exfiltrate password hashes.
