YesWiki: Unauthenticated SQL Injection

Assigner: GitHub_M
Reserved: 15.05.2026 Published: 11.08.2026 Updated: 11.08.2026

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.
