Summary

YesWiki from 4.6.0 before 4.7.0 exposes assembled SQL queries to unauthenticated users, a case of sensitive information inserted into debugging code (CWE-215). Adding the showreq parameter to public Bazar listing API requests reveals table names, JSON storage paths, ACL filter logic and collation. An unauthenticated remote attacker can use this information to plan a targeted SQL injection attack.
