  1. Published11 Aug 2026

Description

YesWiki is a wiki system written in PHP. Prior to version 4.6.4, an unauthenticated SQL injection in the Bazar form-import path (`FormManager::create()`) allows any unauthenticated visitor of a default YesWiki install to inject arbitrary SQL into an `INSERT` statement and read the full database, including `yeswiki_users.password` hashes. Version 4.6.4 fixes the issue.
