What is CVE-2026-104460?

YesWiki versions prior to 4.6.7 suffer from a blind SQL injection vulnerability within the {{newtextsearch}} action. This flaw arises because option IDs used in SQL REGEXP/LIKE clauses are concatenated without adequate escaping in actions/newtextsearch.php. As a result, anonymous attackers can exploit this flaw by inserting a malicious option ID into an editable Bazar list, allowing them to perform search queries that function as a boolean oracle. This exploitation can lead to unauthorized access to sensitive database information, including the admin password hashes stored in the yeswiki_users table.
