CVE-2026-46670YesWiki: Unauthenticated SQL Injection

Updated under an hour ago ()

Does this affect you?

It affects yeswiki. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
