What is CVE-2026-46670?

The YesWiki platform, a PHP-based wiki system, is vulnerable to an unauthenticated SQL injection attack. The flaw exists in the Bazar form-import functionality, specifically within the FormManager::create() method, which permits any unauthenticated users of a default YesWiki installation to execute arbitrary SQL commands. This vulnerability can potentially expose the entire database, including sensitive information such as user password hashes, thereby posing serious risks to the security of the system. It is crucial for users operating versions earlier than 4.6.4 to upgrade promptly to secure their applications.
