[ Description ]Official description
YesWiki before 4.6.7 contains a blind SQL injection vulnerability in the {{newtextsearch}} action because Bazar list option ids are concatenated into SQL REGEXP/LIKE clauses in actions/newtextsearch.php without escaping. Anonymous attackers can plant a malicious option id in an anonymously editable Bazar list and use search requests as a boolean oracle to read arbitrary database data, including admin password hashes from the yeswiki_users table.
